Bismuth-halide oxidative addition and bismuth-carbon reductive elimination in platinum complexes containing chelating diphosphine ligands

Reaction of BiX3 (X = Cl, Br, I) with [PtMe2(P-P)], (1a, P-P = dppm; 1b, P-P = dppe), occurs easily to yield a mixture of platinum(II) complexes [PtMeX(P-P)], 2, and [PtX2(P-P)], 3, and the binuclear complex [Pt2Me2(μ-X)(μ-dppm) 2]X, 4. On the basis of 31P NMR and UV-vis spectroscopy, a mechanism is proposed in which the rate determining step is conversion of the yellowish Pt(II)-BiX3 adduct BiI3·[PtMe 2(dppm)], A, into the Pt(IV)-Bi(III) intermediate [PtMe 2(BiX2)X(P-P)], IM1. Density functional theory (DFT) studies suggest that intermediate IM1 may be formed in acetone solution which undergoes the Bi-C reductive elimination process before formation of complexes 2 and 3. The structures of intermediates IM1 were theoretically determined using DFT calculations. In dilute acetone solution, as monitored by UV-vis spectroscopy, the oxidative addition processes follow first order kinetics. The overall reaction is slower for heavier halide.

Synthesis and structure of gold and platinum menthyl complexes

A Grignard reagent derived from (-)-menthyl chloride has been reported to be a 1:1 mixture of menthyl magnesium chloride and neomenthyl magnesium chloride, which do not interconvert. Addition of an excess of this reagent to Au(PPh3)(Cl) or Pt(dppe)Cl2 gave Au(PPh3)(Men) (1) and Pt(dppe)(Men)(Br) (2), respectively. Crystallographic studies of these first well-characterized transition metal menthyl complexes showed that the menthyl group adopts a conformation with all three substituents in equatorial positions. NMR spectroscopic data for 2 showed that menthyl has a large trans influence, comparable to other alkyl groups. Decomposition of 1 in CDCl 3 gave Au(PPh3)(Cl) and a mixture of menthyl chloride and neomenthyl chloride, while 2 formed the halide complexes Pt(dppe)Cl2, Pt(dppe)Br2, and Pt(dppe)(Br)(Cl) and a mixture of 2-menthene and 3-menthene.
