Ullmann-Type and Related Redox Reactions of Nitrosyl Molybdenum Complexes Bearing a Large-Bite-Angle Diphosphine

The reactions of ArX (X = Cl and Br) with [Mo(NO)(P?P)(NCMe)3][BArF4] P?P = 2,2?-bis(diphenylphosphanyl)diphenyl ether (DPEphos), BArF4 = tetrakis[3,5-bis(trifluoromethyl)phenyl]borate at 120 C resulted in the formation of biphenyl (through CAr-CAr reductive homocoupling) and the dinuclear halide salts [Mo2(NO)2(P?P)2(NCMe)2(mu-X)2][BArF4]2 (X = Cl, 1; Br, 2). Complexes 1 and 2 potentially show cisoid (1c and 2c) and transoid (1t and 2t) regioisomerism with respect to the position of the NO ligand. The crystal-structure determinations of 1 and 2 revealed the presence of the transoid isomers 1t and 2t and MI-MI bonding in both cases. A proposed mechanism for the formation of 1t and 2t involves reductive CAr-CAr coupling to form biphenyl from two Ph-MoII centers. In addition, the complexes Mo(NO)(P?P)(CO)2Cl (3) and [Mo(NO)(mer-kappa3-P,P,O-DPEphos)Cl(PR3)] (R = Me, 4; Ph, 5) were obtained through the reductions of [Mo2(NO)2(P?P)2Cl4(mu-Cl)2]. The mild oxidation of [Mo0(NO)(P?P)(NCMe)3][BArF4] P?P = 2,2?-bis(diphenylphosphanyl)diphenyl ether, BArF4 = tetrakis[3,5-bis(trifluoromethyl)phenyl]borate with aryl halides affords dinuclear [MoI2(NO)2(P?P)2(NCMe)2(mu-X)2][BArF4]2 species and biphenyl through an Ullmann-type dinuclear homocoupling process. The complexes are characterized spectroscopically and by X-ray diffraction studies.

Vinylidene, vinyl, and carbene ruthenium complexes with chelating diphosphanes as ligands

The ruthenium vinylidenes [RuCl2(=C=CHR) (PR?3)2] (1, 2) react with 1,2-C2H4(PCy2)2 (3) to give the chelate complexes [RuCl2(=C=CHR)(kappa2-3)] (4, 5) by displacement of the two monodentate phosphane ligands. In contrast, the reaction of the hydrido compound [RuHCl(=C=CH2)(PCy3)2] (6) with excess 3 proceeds by migration of the hydride to the Calpha carbon atom of the vinylidene unit and affords the six-coordinate vinyl complex trans-[RuCl(CH=CH2)(kappa2-3)2] (7). Protonation of 7, followed by addition of NH4PF6, yields the cationic ruthenium carbene trans-[RuCl(=CHCH3)(kappa2-3)2] PF6 (8), together with small quantities of the hydrido compound [RuH(kappa2-3)2]PF6 (9). The Grubbs catalyst [RuCl2(=CHPh)(PCy3)2] (10) reacts with both 3 and [Fe(eta5C5H4PPh2)2] (11), also by ligand substitution, to give the corresponding chelate complexes [RuCl2(=CHPh)(kappa2-3)] (12) and [RuCl2(=CHPh)(kappa2-11)] (13); the latter has been characterized by X-ray crystal structure analysis.

Kinetics of complex formation between palladium(II) acetate and bis(diphenylphosphino)ferrocene

The kinetics of complex formation between palladium(II) acetate, and 1,1′-bis(diphenylphosphino)ferrocene, dppf, in two different deuterated solvents CDCl3 and DMSO-d6 were investigated using 31P NMR spectroscopy. The mole ratio and the 31P-chemical shifts in DMSO-d6 solution revealed the formation of an intermediate, which is gradually converted into the more stable [Pd(dppf)OAc)2] species with a dppf acting as a chelate ligand. In the chloroform solution however, the interaction of metal ion and the ligand resulted directly in the formation of [Pd(dppf)OAc)2] species with a chelating dppf. The rate constant for the complexation reaction was evaluated from computer fitting of the corresponding integration-time data.

Synthetic and solution calorimetric investigations of chelating phosphine ligands in Ru(allyl)2(PP) complexes (PP = diphosphine)

Reaction enthalpies of (COD)Ru(allyl)2 (COD = eta4-1,5-cyclooctadiene; allyl = 2-methylpropenyl) with a series of bidentate phosphines (dppm, dppf, dppe, dppb, dppp, depe, dmpe) have been measured by anaerobic solution calorimetry. The relative stability of the resulting complexes is strongly influenced by the electronic donor properties of the bidentate phosphine ligand. Reactions involving ligands that are better sigma donors result in higher enthalpy values and, therefore, more thermodynamically stable complexes. Additionally, the synthesis and characterization of two new ruthenium allyl complexes Ru(allyl)2(dppf) (3) and Ru(allyl)2(depe) (8) and the X-ray crystal structure of 3 are reported.

Synthesis and Chemistry of Dithiadiazole Free Radicals [4-(4′-C5H4N)CN2S2] and [4(3′-5H4N)CN2S2] X-ray crystal structures of Pd3 -SNC(Ar’)NS-S,S’2(PPh3)4] (Ar’=4′-C5H4N,4′-C5H4NBEt3 and 3′-C5H4NBEt3)

Two new 1,2,3,5-dithiadiazoles, [4-(4′-C5H4N)CN2S2] (L1) and [4- (3′-C5H4N)CN2S2] (L2), with different pyridyl groups at the 4-position were prepared. As Lewis bases, the dithiadiazoles reacted with Lewis acids via their pyridyl groups to form acid-base adducts with retention of the five-membered dithiadiazole ring. Ligands L1 and L2 reacted with excess triethylborane to give L1BEt3 and L2BEt3 (1a and 1b) and with Mn(CO)5Br to give the fac-Mn(CO)3Br(L1)2 (2a) and fac-Mn(CO)3Br(L2)2 (2b) complexes. When reacted with Pd0 complexes, namely, Pd(PPh3)4 and a mixture of [Pd2(dba)3] and dppf, the dithiadiazoles underwent ring-opening reaction by reductive cleavage of the S-S bond of the dithiadiazole ring. The resulting formation of Pd-S bonds gave the corresponding trinuclear complexes [Pd3a??I?-SNC (4′-C5H4N)NS-S,S’a??2(PPh3)4] (3a), [Pd3a??I?-SNC(3′- C5H4N)NS-S,S’a??2(PPh3)4] (3b), and [Pd3a??I?-SNC(4′-C5H4N)NS- S,S’a??2(dppf)2] (4) [dba = dibenzylideneacetone, dppf = 1,1′- bis(diphenylphosphanyl)ferrocene]. Complexes 3a and 3b reacted with excess triethylborane to give the corresponding acid-base adducts [Pd3a??I?-SNC(4′- C5H4NBEt3)NS-S,S’a??2(PPh3)4] (5a) and [Pd3a??I?SNC(3′-C5H4NBEt3)NS- S,S’a??2(PPh3)4] (5b.) Complex 3a reacted with Mn(CO)5Br to give a??[Pd3a??I?-SNC(4′-C5H4N)NS-S,S’a??2(PPh3)4][MnBr(CO)3]a??n (6). The structures of 3a, 5a, and 5b were established by X-ray crystallography.

Advances in metal-assisted non-electrophilic fluoroalkylation reactions of organic compounds

Metal-assisted trifluoromethylation and perfluoroalkylation reactions are probably one of the first approaches employed to achieve fluoroalkyl-group substitutions of organic substrates through the use of metals such as copper. Fluoroalkylation reactions of both aromatic and aliphatic substrates involving the employment of perfluoroalkyl halides RfX in conjunction with metallic species, and nucleophilic fluoroalkylating reagents in the presence of metals or organometallic species will be studied. Fluoroalkylation reactions utilizing electrophilic fluoroalkylating reagents in the presence of transition metals or trifluoromethylthiolation reactions will not be the subject of this article. Recently emerging literature (2011-present), with special emphasis on updates from previous review articles on the metal-mediated fluoroalkylation of aromatic substrates will be dealt with.

Chalcogen-Chalcogen Bonding Catalysis Enables Assembly of Discrete Molecules

Despite the observation of noncovalent interactions between chalcogen atoms in X-ray crystal structures, catalysis that harnesses the power of such chalcogen-chalcogen bonding interactions to produce advanced molecules remains an unresolved problem. Here, we show that a class of extraordinary chalcogen-bonding catalysts enables assembly of discrete small molecules including three beta-ketoaldehydes and one indole, leading to the construction of N-heterocycles in a highly efficient manner. The strong activation ability of these rationally designed catalysts provides a general solution to the intrinsic limitations of chalcogen bonding catalysis.

Metathesis-active ligands enable a catalytic functional group metathesis between aroyl chlorides and aryl iodides

Current methods for functional group interconversion have, for the most part, relied on relatively strong driving forces which often require highly reactive reagents to generate irreversibly a desired product in high yield and selectivity. These approaches generally prevent the use of the same catalytic strategy to perform the reverse reaction. Here we describe a catalytic functional group metathesis approach to interconvert, under CO-free conditions, two synthetically important classes of electrophiles that are often employed in the preparation of pharmaceuticals and agrochemicals?aroyl chlorides (ArCOCl) and aryl iodides (ArI). Our reaction design relies on the implementation of a key reversible ligand C?P bond cleavage event, which enables a non-innocent, metathesis-active phosphine ligand to mediate a rapid aryl group transfer between the two different electrophiles. Beyond enabling a practical and safer approach to the interconversion of ArCOCl and ArI, this type of ligand non-innocence provides a blueprint for the development of a broad range of functional group metathesis reactions employing synthetically relevant aryl electrophiles.
