Platinum complex with

Because their rates of substitution tue convenient for study, most work has been done with platinum complexes, and for lhe.se it is found that ligands can be airanged in a fairly consistent order indicating their relative abilities to labilize ligands irans to themselves ...

Cyclometallation of thiophene imine 110 with platinum complex 111 proceeded to give metallacycle 112 via an intramolecular C-H insertion on the thiophene ring . 

Rhodium (I) complexes of chiral phosphines have been the archetypical catalysts for the hydrocarbonylation of 1-alkenes, with platinum complexes such as (61) making an impact also in the early 1990s[1461. More recently, rhodium(I)-chiral bisphosphites and phosphine phosphinites have been investigated. Quite remarkable results have been obtained with Rh(I)-BINAPHOS (62), with excellent ee s being obtained for aldehydes derived for a wide variety of substrates1 471. For example, hydroformylation of styrene gave a high yield of (R)-2-phenylpropanal (94% ee). The same catalyst system promoted the conversion of Z-but-2-ene into (5)-2-methylbutanal (82% ee). 

The addition of Si—H bonds and the reactions of silyls with platinum complexes is of significance because of the early discovery of chloroplatinic acid as a hydrosilylation catalyst.53 This section focuses on the formation of hydrides from silanes. 

The first enantioselective alkylation of l,3-diphenylprop-2-enyl ethylcarbonate 19 with sodio dimethyl malonate using a ruthenium-based catalyst has been reported [113]. As shown in Eq. 2, a planar-chiral cyclopentadienylruthenium complex 35 catalyses the addition in excellent yield and enantioselectivity. The complex also catalyzed the amination although in lower ee (74%). Other derivatives of the complex also gave excellent results. Interesting selectivity (90-95% ee) has been obtained with platinum complexes though the conversions are low (25-39%) [114,115]. 

The bis-enolate Cp2Ti[OC(Ph)=CHPPh2]2 has been synthesized by reaction of Cp2TiCl2 with the Li salt of the phosphinoenolate ligand. The complex reacts with platinum complexes to afford heterobimetallic derivatives.1548...
