Heats of reaction of pyridine, triphenylphosphine, and triphenyl phosphite with the chloro-, bromo-, and iodo-1,5-cyclooctadienerhodium(I) dimers and dichlorobis(benzonitrile)palladium(II)

The heats for the following reactions in dichloromethane are reported: [RhX(COD)]2 + 2B → 2[RhX(COD)(B)]; [RhX(P-(OC6H5)3)2]2 + 2P(OC6H5)3 → 2[RhX(P(OC6H5)3)3]; [RhX(COD)2] + 2P(OC6H5)3 → [Rh2X2(COD)(P(OC6H5) 3)2] + COD; [Rh2X2(COD)(P(OC6H5) 3)2] + 2P(OC6H5)3 → [RhX(P(OC6H5)3)2]2 + COD; [PdCl2(C6H5CN)2] + 2B → [PdCl2B2] + 2C6H5CN; and [PdCl2(COD)] + 2P(OC6H5)3 → [PdCl2(P(OC6H5)3)2] + COD (B = pyridine, triphenylphosphine; X = Cl, Br, I; COD = 1,5-cyclooctadiene). Relative displacement energies are for the rhodium compounds, triphenyl phosphite ? 1,5-cyclooctadiene and triphenylphosphine > pyridine, and for the palladium compounds, triphenylphosphine > triphenyl phosphite > pyridine ? cyclooctadiene. Arguments are given that solvent-solute enthalpic contributions are not predominant in the displacement energies. For a given reaction, the effect of varying the halogens upon the observed enthalpies is very small or nonexistent. Equilibrium constants for the first reaction are too high to measure when B = triphenylphosphine and are approximately 5 × 104 when B = pyridine.

Kinetic studies of some substituted hexarhodium carbonyl clusters

Reactions of the halides X- (X- = chloride, bromide or iodide) with the substituted cluster Rh6(CO)15(PPh 3) in oxygen-free chloroform lead to [Rh5(CO) 14(PPh3)]-, Rh(CO)2(PPh 3)2X and [Rh(CO)2X2]- in the molar ratios 2 : 1 : ～13, Oxidation by the solvent is assumed to lead to most of the Rh(I) product, and the stoichiometry for reactions with I - can be defined as 4Rh6(CO)15(PPh 3) + 27I- + 12CHCl3 → 2[Rh 5(CO)14(PPh3)]- + Rh(CO) 2(PPh3)2I + 13[Rh(CO)2I 2]- + 6C2H2Cl4 + 4CO + 12Cl-. This can be rationalized quite simply with the aid of a few generally justifiable assumptions. Rate constants for reactions with bromide increase to a limiting value with increasing [Br-] in a way that shows that breaking of one Rh-Rh bond, with an unusual closo to nido structural change, is rate determining. This opening of the cluster might be spontaneous or solvent induced. To complete the reaction, the bromide has to compete with the reverse nido to closo change. The same closo to nido change is also a major rate determining step for reactions with P(OPh)3 in oxygen-free solutions, and for reactions with bromide in oxygenated solutions in the presence of trifluoroacetic and some other acids. The limiting rates increase slightly with increasing basicity of the ligands P(p-XC6H 4)3 along the series X = F3C, Cl, F, H and MeO. Activation parameters for these reactions are reported.

Regioselectivity in the rhodium catalysed 1,4-hydrosilylation of isoprene. Aspects on reaction conditions and ligands

The regioselectivity in the Rh catalysed 1,4-hydrosilylation of isoprene was investigated. Variation of solvents and temperature did not significantly affect the isomer distribution between tail-product (I) and head-product (II). The choice of ligands had

A facile route to carbonylhalogenometal complexes (M = Rh, Ir, Ru, Pt) by dimethylformamide decarbonylation

Dimethyl formamide (DMF) can be a convenient source of the carbonyl ligand in the coordination chemistry of rhodium, ruthenium, iridium, and platinum. We have undertaken a thorough study concerning the course of this reaction. In a first step, DMF-containing complexes are produced, which is usually accompanied by chloride redistribution. Then, upon refluxing, carbonyl species in the same oxidation state are obtained, presumably as a result of HCl-mediated DMF decomposition. Provided that water levels are kept low, reduction can occur to provide the complexes [NH2(CH3)2][RhCl2(CO) 2], [NH2(CH3)2][RuCl3(CO) 2(DMF)], [RuCl2(CO)2(DMF)2], and [NH2(CH3)2][IrCl2(CO) 2]. In the case of platinum, reduction is not effective and [NH2(CH3)2][PtCl3(CO)] is obtained. No carbonylpalladium species can be synthesized in this way, the reaction producing copious amounts of colloidal metal. Adding phosphanes to these chlorocarbonyl-containing solutions allows easy, one-step syntheses of a variety of complexes.

New insight into role of ortho-metallation in rhodium triphenylphosphite complexes. Hydrogen mobility in hydrogenation and isomerization of unsaturated substrates

The hydrogen transfer from two rhodium(I) hydrido complexes HRh{P(OPh)3}4 and HRh(CO){P(OPh)3}3 to methyl acrylate and/or allylbenzene leads to the formation of ortho-metallated complexes Rh{P(OC6H4)(OPh)2}{P(OPh)3} 3 (I) and Rh{P(OC6H4)(OPh)2}(CO){P(OPh)3} 2 (II), respectively. During these reactions unsaturated substrates, methyl acrylate or allylbenzene undergo stoichiometric hydrogenation. A similar reaction was also observed for HRh{P(OR)3}4 complexes (R=3-CH3C6H4, 4-CH3C6H4). The complex HRh{P(OPh)3}4 catalyses the isomerization of hex-1-ene to hex-2-ene in the absence of H2; however at 1 atm of H2 the formation of hexane is observed. Hydrido complexes of the type HRh{P(OR)3}4 in D2 atmosphere undergo H/D exchange at the ortho position of coordinated triarylphosphite. Deuteration of the ortho protons in complexes with R=Ph, 3,5-(CH3)2C6H3 and 4-CH3C6H4 is total, whereas only one ortho hydrogen is replaced in the case of R=3-CH3C6H4. The formation of an ortho-metallated chelating ring causes a downfield shift in the 1H-NMR signal of one proton from the phenyl ring to δ ca. 8 ppm.
