Reactions of Ru(Cp*) complexes with P(o-tolyl)3

Reaction of [Ru(Cp*)(CH3CN)3](PF6) with P(o-tolyl)3 affords [Ru(Cp*){(eta6-o-tolyl)P(o-tolyl)2}](PF6) (4) in which the P-atom is not coordinated to the metal. The solid-state structure of 4 has been determined. A related reaction with P(p-tolyl)3 reveals a small quantity [Ru(Cp*){(eta6-p-tolyl)P(o-tolyl)2}](PF6), in solution, but mostly the expected bis-phosphine complex. Reaction of the Ru(IV) dication, [Ru(Cp*)(eta3-PhCHCHCH2)(DMF)2](PF6)2, with P(o-tolyl)3 gives a mixture of the phosphonium salt, C6H5CH{double bond, long}CHCH2P(o-tolyl)3 (9) and the dication [Ru(Cp*) (eta6-C6H5CH{double bond, long}CHCH2P(o-tolyl)3)](PF6)2 (10). Salt 9 forms via attack of the P-atom on the allyl ligand. The latter product results from complexation of 9 via the phenyl group of the former allyl ligand. It would seem that the sterically demanding P(o-tolyl)3 ligand is not readily compatible with the Ru(Cp*) fragment, in either the +2 or +4 oxidation state. Detailed NMR studies are reported.

Palladium(II) and platinum(II) complexes with tridentate iminophosphine ligands; synthesis and structural studies

The previously synthesised Schiff-base ligands 2-(2-Ph2PC 6H4N=CH)-R?-C6H3OH (R? = 3-OCH3, HL1; 5-OCH3, HL2; 5-Br, HL3; 5-Cl, HL4) were prepared by a faster, more efficient route involving a microwave assisted co-condensation of 2-(diphenylphosphino) aniline with the appropriate substituted salicylaldehyde. HL1-4 react directly with MIICl2 (M = Pd, Pt) or Pt III2(cod) affording neutral square-planar complexes of general formula [MIICl(eta3-L1-4)] (M = Pd, Pt, 1-8) and [PtIII(eta3-L1-4)] (M = Pd, Pt, 9-12). Reaction of complexes 1-4 with the triarylphosphines PR3 (R = Ph, p-tolyl) gave the novel ionic complexes [PdII(PR 3)(eta3-L1-4)]ClO4 (13-20). Substituted platinum complexes of the type [PtII(PR 3)(eta3-L1-4)]ClO4 (R = P(CH 2CH2CN)3 21-24) and [PtII(P(p-tolyl) 3)(eta3-L3.4)]ClO4 (25 and 26) were synthesised from the appropriate [PtIICl(eta3- L1-4)] complex (5-8) and PR3. The complexes are characterised by microanalytical and spectroscopic techniques. The crystal structures of 3, 6, 10, 15, 20 and 26 were determined and revealed the metal to be in a square-planar four-coordinate environment containing a planar tridentate ligand with an O,N,P donor set together with one further atom which is trans to the central nitrogen atom.

Structural relationships between o-, m- and p-tolyl substituted R 3EI2 (E = As, P) and [(R3E)AuX] (E = As, P; X = Cl, Br, I)

The compounds R3EI2 (R = o-tolyl, E = As, 1a; R = m-tolyl, E = P 1c; R = p-tolyl, E = As, 1d, P, 1e), which display the charge transfer spoke structure, and [(o-tolyl3As)AuCl] 2 have been synthesised and their solid state structures compared to the related complexes [(R3P)AuX] (R = o-tolyl, X = Cl, I, Ia; Br, II; I, III; R = m-tolyl, X = Cl, IV; R = p-tolyl, X = Cl, V, Va; Br, VI; I, VII) on the basis of a similarity of their molecular shape and volume. All of the new compounds 1a, 1c-1e and 2 have been fully spectroscopically characterised and by single crystal X-ray crystallography. The sterically demanding exo3o-tolyl ring conformation is observed for 1a, which is comparable to that reported for o-tolyl3PI21b, with a long As-I bond 2.7351(14) A and short I…I distance 2.9528(11) A. The exo3o-tolyl ring conformation is maintained on complexation to gold(i) in 2, but has no significant impact on the expected bond lengths, with As-Au 2.3443(15) A and Au-Cl 2.284(4) A. The exo3 conformation appears to be stabilised in both cases by the formation of a six-fold edge-to-face (EF) 6 embrace. It is found that in some cases the structures of the dihalogen adducts and the gold(i) complexes are isomorphous indicating that ligand packing requirements are most significant i.e. for 1c and IV. Where the structures digress this is due either to the greater ability of the dihalogen adduct to engage in hydrogen bonding 1a, b and I-III; or subtle changes in the nature of the tolyl ring embraces 1d, e and V-VII. Subtle changes in the nature of the tolyl ring embraces also account for the different polymorphs I and Ia and V and Va. There is no credible evidence to suggest that the aurophilic contact, seen in only one polymorph Va, exerts any influence on the overall crystal packing. The structural comparisons presented here add further to the applicability of the recently recognised structural mimicking ability of the R3PX2 systems and [R3PAuX] complexes, and that the aurophilic contact is a poor supramolecular synthon.

Diastereoselective substitution of PR3 for Co in carbohydrato- and menthyloxycarbene complexes of manganese – Synthesis of chiral-at-metal carbene and carbyne complexes

The substitution of PR3 (R = C6H4CH3-p, C6H4Cl-p, C6H11, OCH3) for a CO ligand in chiral carbohydratocarbene complexes [(eta5-C5H5)(CO) 2Mn=C(OR*)Ph] [OR* = alpha- (1alpha) and beta-mannofuranosyl (1beta), (-)-menthyloxy (9)] proceeds diastereoselectively. The diastereoselectivity depends on PR3 and on the OR* substituent and ranges from 12% de (R = OCH3) to 80% (R = C6H4CH3-p). In contrast, the reaction of 1beta with P(OPh)3 is non-selective. The diastereoselectivity generally increases with increasing nucleophilicity of PR3 snd decreases in the series 1beta > 1alpha > 9. The highest diastereoselectivity was observed in the reaction of 1beta with P(C6H4CH3-p)3. Predominantly, the isomer with the (S) configuration at the metal [(SMn)-2beta] was formed which could be separated from the diastereomeric mixture by chromatography and be obtained in a pure form. Subsequent reaction of (SMn)-2beta with BF3 afforded the carbyne-manganese complex (SMn)-[(eta5-C5H5){P(C 6H4CH3-p)3}(CO)Mn?CPh]BF 4. VCH Verlagsgesellschaft mbH, 1996.

Investigation of non-Rehm-Weller kinetics in the electron transfer from trivalent phosphorus compounds to singlet excited sensitizers

Singlet excited states (1S* and 1S +*) of neutral and monocationic sensitizers, S and S +, respectively, were quenched by electron transfer (ET) from a variety of trivalent phosphorus compounds (Z3P). The quenching rate constants kq, which are equal to the rate constants kET of the ET from Z3P to 1S* or 1S+*, were determined by the Stern-Volmer method. The logarithm of kET was plotted against free-energy change DeltaG0 of the ET. The plot deviated upward from the line predicted by the Rehm-Weller (RW) theory in the endothermic region, the deviation being larger in the ET to a neutral acceptor 1S* than in the ET to a cationic acceptor 1S+*. Such a kinetic behavior is in sharp contrast to that observed in the ET from amines (R 3N), where the ET to either neutral or cationic acceptor takes place according to the RW prediction. The ET from a donor, Z3P or R 3N, to a neutral acceptor 1S* is a charge-separation type, during which electrostatic attraction between the donor and the acceptor is generated, whereas the ET to a cationic acceptor 1S+* is a charge-shift type, which results in neither electrostatic attraction nor repulsion. Difference in kinetics-energetics relationship by the type of ET, which is not recognized in the ET from R3N donor, becomes “visible” when Z 3P is used as a donor. Copyright 2013 John Wiley & Sons, Ltd. The rate constants kET of electron transfer from trivalent phosphorus compounds to singlet photoexcited sensitizers were determined by the Stern-Volmer method. LogkET-DeltaG0 plots were found to deviate upward from the line predicted by the Rehm-Weller theory, with deviation being larger in ET to neutral acceptors than in ET to cationic acceptors.

Mononuclear ruthenium complexes containing two different phosphines in trans position: I. Synthesis and spectroscopic characterization

New mononuclear ruthenium complexes Ru(CO)2(Y)(Y?)(P nBu3)[P(p-XC6H4)3] (Y, Y? = H, CH3COO; X = CH3O, CH3, H, F, Cl), all containing a PnBu3 in trans position to a triarylphosphinic ligand differently substituted in the para position, were synthesized. These ligands were chosen in order to change the basicity of the phosphine in trans to the PnBu3, without relevant steric changes. Spectroscopic data of the new complexes were correlated with the basicity of the triarylphosphines or with the mesomer effect of the substituent in the para position of the aromatic ring. The presence of two different phosphines into a mononuclear ruthenium complex seems an interesting model to study the “trans effect” for octahedral species.

Direct oxygen atom transfer versus electron transfer mechanisms in the phosphine oxidation by nonheme Mn(IV)-oxo complexes

Direct oxygen atom transfer from a nonheme Mn(iv)-oxo complex, [(Bn-TPEN)MnIV(O)]2+, to triphenylphosphine (Ph3P) derivatives occurs with a significant steric effect resulting from the ortho-substituents on the phenyl group of the Ph3P derivatives, whereas the phosphine oxygenation by a Mn(iv)-oxo complex in the presence of HOTf occurs via an electron transfer mechanism without the substrate-steric effect.
