Substituent effects on aurophilicity and pi-pi interaction in crystals of arylphosphine-Au(I) derivatives. Synthesis and X-ray structural studies of compounds (CX3C6H4)3P-Au-X and {(CF3)2C6H3}3P-Au-X

Substituent effects on aurophilic interactions have been explored by single-crystal X-ray diffraction methods for a series of Au(I) complexes of monodentate phosphines, R?3P-Au-X (X = Cl, Sph, and Spy). When a CF3 substituent is introduced at a meta position of the phenyl ring in (C6H5)3P, aurophilicity has been accrued in ClAuP(m-CF3C6H4)3. However, aurophilicity has been weakened by introducing two CF3 groups at both meta positions. When a CF3 substituent is substituted for a H atom in the para position or when a CH3 substituent is introduced in the meta and/or para positions, such an effect has not been observed for R?3PAuCl and R?3PAuSph. Most dimers constructed by aurophilicity appear to be reinforced by pi-pi interactions between the phenyl ring of the Sph ligand or the pyridine ring of the Spy ligand and one of the phenyl rings in the R?3P ligand. A novel ladder-like supra molecular architecture is created in the crystal of {3,5-(F3C)2C6H3}3 PAuSph, and a tetramer is formed in the crystal of (C6H5)3PAuSpy by aurophilic and pi-pi interactions. Substituent effects on important bond lengths have been discussed.

Photoinduced Synthesis of P-Perfluoroalkylated Phosphines from Triarylphosphines and Their Application in the Copper-Free Cross-Coupling of Acid Chlorides and Terminal Alkynes

A practical synthesis yielding P-perfluoroalkylated phosphines from triarylphosphines and perfluoroalkyl iodides has been developed. The photoinduced reaction involves the substitution of aryl groups on the phosphorus atom with perfluoroalkyl groups to successfully afford P-perfluoroalkylated phosphines. In addition, the P-perfluoroalkylated phosphines were found to promote the Cu-free cross-coupling reaction of acid chlorides with terminal alkynes.

Structural properties and dissociative fluxional motion of 2,9-dimethyl-1,10-phenanthroline in platinum(II) complexes

A dynamic 1H NMR study has been carried out on the fluxional motion of the symmetric chelating ligand 2,9-dimethyl-1,10-phenanthroline (Me2-phen) between nonequivalent exchanging sites in a variety of square-planar complexes of the type [Pt(Me)(Me2-phen)(PR 3)]BArf, 1-14, (BArf = 8[3,5-(CF3)2C 6H3]4. In these compounds, the P-donor ligands PR3 encompass a wide range of steric and electronic characteristics [PR3 = P(4-XC6H4)3, X = H 1, F, 2, Cl 3, CF3 4, MeO 5, Me 6; PR3 = PMe2(C 6H5)2 7, PMe2(C6H 5) 8, PMe3 9, PEt3 10, P(i-Pr)3 11, PCy(C6H5)2 12, PCy2(C 6H5) 13, PCy3 14]. All complexes have been synthesized and fully characterized through elemental analysis, 1H and 31P{1H} NMR. X-ray crystal structures are reported for the compounds 8, 11, 14, and for [Pt-(Me)(phen)(P(C6H 5)3)]PF6 (15), all but the last showing loss of planarity and a significant rotation of the Me2-phen moiety around the N1-N2 vector. Steric congestion brought about by the P-donor ligands is responsible for tetrahedral distortion of the coordination plane and significant lengthening of the Pt-N2 (cis to phosphane) bond distances. Application of standard quantitative analysis of ligand effects (QALE) methodology enabled a quantitative separation of steric and electronic contributions of P-donor ligands to the values of the platinum-phosphorus 1JPtP coupling constants and of the free activation energies DeltaG? of the fluxional motion of Me2-phen in 1-14. The steric profiles for both 1JPtP and DeltaG? show the onset of steric thresholds (at cone angle values of 150 and 148, respectively), that are associated with an overload of steric congestion already evidenced by the crystal structures of 11 and 14. The sharp increase of the fluxional rate of Me2-phen can be assumed as a perceptive kinetic tool for revealing ground-state destabilization produced by the P-donor ligands. The mechanism involves initial breaking of a metal-nitrogen bond, fast interconversion between two 14-electron three-coordinate T-shaped intermediates containing eta1-coordinated Me2-phen, and final ring closure. By use of the results from QALE regression analysis, a free-energy surface has been constructed that represents the way in which any single P-donor ligand can affect the energy of the transition state in the absence of aryl or pi-acidity effects.

Solubility of triphenylphosphine, tris(p-fluorophenyl)phosphine, tris(pentafluorophenyl)phosphine, and tris(p-trifluoromethylphenyl)phosphine in liquid and supercritical carbon dioxide

The solubility of the solid substances triphenylphosphine P(C6H5)3, tris(p-fluorophenyl)phosphine P(C6H4F)3, tris(pentafluorophenyl)phosphine P(C6F5)3, and tris(p-trifluoromethylphenyl)phosphine P[4-(CF3)C6H4]3 in CO2 was measured as a function of pressure at 300.0 K, 310.0 K, 320.0 K, and, in the case of triphenylphosphine, at 330.0 K. For this purpose, a new recirculation view cell apparatus coupled to a high-performance liquid chromatograph was constructed. The solubility S of triphenylphosphine was measured up to 30.3 MPa and up to a maximum of 0.119 mol/L, tris(pentafluorophenyl)phosphine up to 12.0 MPa and 0.246 mol/L, tris(p-fluorophenyl)phosphine up to 18.9 MPa and 0.468 mol/L, and tris(p-trifluoromethylphenyl)phosphine up to 12.0 MPa and 0.470 mol/L. The increasing degree of fluorination in these four substances led to an increase of their solubility in carbon dioxide.

In situ high-pressure NMR studies of Co2(Co)6[P(p- CF3C6H4)3]2 in supercritical carbon dioxide: Ligand substitution, hydrogenation, and hydroformylation reactions

The dimeric cobalt complex Co2(CO)6[P(p-CF 3C6H4)3]2 (1) reacts reversibly with hydrogen to produce HCo(CO)3[P(p-CF3C 6H4)3] (4). The carbonyl and the phosphine ligands of both 1 and 4 are very labile. Compound 1 reacts with CO to give Co2(CO)7[P(p-CF3C6H 4)3] (2), and compound 4 reacts with CO and P(p-CF 3C6H4)3 (L) to give HCo(CO) 4 (5) and HCo(CO)2[P(p-CF3C6H 4)3]2 (6), respectively. The 31P NMR studies show that, in the presence of 1, the line width of the 31P resonance of L is temperature dependent, and at constant temperature, its broadening is proportional to the square root of the concentration of 1. This broadening is attributed to its exchange reaction with the mononuclear cobalt radical (CO)3LCo¡¤ (3), which is generated by the homolysis of 1. Compound 1 catalyzes the hydroformylation of olefins in supercritical carbon dioxide. In contrast to the unsubstituted Co2(CO)8, the phosphine-modified catalyst system is stable under low CO pressures and the hydroformylation reactions can be carried out at low pressures. In situ monitoring of 31P and 59Co NMR spectra of the solution shows that the phosphine-containing hydrido cobalt complexes 4 and 6 are the only hydrido cobalt complexes present in detectable concentrations in 1-catalyzed hydroformylation reactions; nevertheless, the possibility that the observed activity for 1 comes primarily from the more active HCo(CO) 4, present in concentrations below detectable limits, has not been rigorously excluded.

Ruthenium(IV)-Oxo Complexes: The Novel Utilization of Tertiary Pnictogen Ligands

The novel complexes <(bpy)2(PnR3)RuIV(O)>(ClO4)2 (where bpy = 2,2′-bipyridine and PnR3 = tertiary phosphine or arsine) have been generated from the analogous ruthenium(II)-aquo species, through electrochemical means or by the addition of two equivalents of cerium(IV).Characterization of the ruthenium(II)-aquo and ruthenium(IV)-oxo complexes was accomplished through UV-vis spectroscopy, IR spectroscopy, 18O labeling experiments, NMR spectroscopy, cyclic voltammetry, coulometry, and conductivity measurements.These complexes are stable both in the solid state and in various solutions, where the phosphine and arsine ligands do not undergo oxidation by the ruthenium(IV)-oxo center.Cyclic voltammetric measurements of the ruthenium(II)-aquo complexes are consistent with the following redox couples: RuIV=O/RuIII-OH/RuII-OH2, which can be described as two sets of concomitant one-electron, one-proton transfers.The ruthenium(IV)-oxo complexes act as selective oxidation reagents toward organic substrates, where the nature of the pnictogen ligand greatly affects the rate of substrate oxidation.In addition, the use of a pnictogen ligand cis to the oxo moiety in these complexes simplifies the mechanism of substrate oxidation relative to other ruthenium-based oxidants.Finally, pnictogen ligands exert unusual effects on the redox chemistry of ruthenium(IV)-oxo complexes, including hydrophobic selectivity and aerobically driven substrate oxidation catalysis.

New methods for the synthesis of ArPdL2I (L = tertiary phosphine) complexes

Organopalladium ArPdL2I (L = tertiary phosphine) complexes (1) can be synthesized in one step from the precursors Pd2(dba)3¡¤C6H6 (2) (dba = t,t-dibenzylideneacetone) and (eta3-allyl)PdCp (3) (Cp = eta5-cyclopentadienide). Two advantages over previous synthetic methods are that this route requires only stoichiometric amounts of phosphine and that the desired complexes are easily isolated from reaction byproducts. The scope and generality of these reactions are investigated, and the synthesis of a number of new organic- and water-soluble complexes utilizing this methodology is discussed. Improved syntheses of water-soluble ligands P(C6H5)2(4-SO3KC6H 4) (5) and As(C6H5)2(4-SO3KC6H 4) (6) are presented as well.

Oxidation-resistant cyclophosphazene fluid including triarylphosphine or phosphine oxide

The oxidation resistance of a cyclophosphazene-based fluid (such as a lubricant or a hydraulic fluid) can be improved by the addition to the fluid of an oxidation-inhibiting amount of an aryl phosphine or phosphine oxide. The aryl phosphine or phosphine oxide is preferably present in an amount of about 0.01 to about 5 percent by weight. The aryl phosphine or phosphine oxide can be (a) a symmetric triarylphosphine of formula R3 P, wherein R is 4-trifluoromethyl phenyl, 3-trifluoromethyl phenyl, 3-trifluoromethoxy phenyl, 3-(3-trifluoromethylphenoxy) phenyl, 3-(perfluoro-2, 5-dimethyl-3, 6-dioxanonyl) phenyl or 1-naphthyl; (b) an oxide of any of these symmetric triarylphosphines; or (c) 1, 3-bis(diphenylphosphino) benzene. The cyclophosphazene fluid component is preferably a (fluorinated phenoxy) (3-perfluoroalkylphenoxy)-cyclic phosphazene of the general formula (I): STR1 wherein n is 3 to 7, inclusive; wherein R is individually in each occurrence fluorinated phenoxy or 3-perfluoroalkylphenoxy; and wherein the ratio of fluorinated phenoxy to 3-perfluoroalkylphenoxy is about 1:5 to 1:1 inclusive. Although useful as antioxidants in other fluids such as polyphenyl ethers, perfluorinated aliphatic polyethers and polyol esters, the antioxidant activity of the defined aryl phosphines and phosphine oxides in cyclophosphazene fluids is unexpected because of the significant difference in the pathways of oxidative degradation between the cyclophosphazenes and these other fluids.
