摘要: Abstract Reaction of cis -[Ptph 2 (SMe ) ] with Me PCH PMe (dmpm) gave -[PtPh (dmpm-P) ( 1 or cis,cis -[Pt Ph 4 (μ-dmpm) and reaction [Pt (μ-SMe -[Ph Pt(μ-dmpm) PtMe 3 ). trans -[PtClR(SMe , PtClR], R = 5 6 ), in polar solvents, these isomerized to give [Ph PtR] + Cl − . When Me, further isomerization via the phenyl group transfer [PhMePt(μ-dmpm) PtPh] Oxidative addition methyl iodide occurred reversibly at -[PtMe P unit fac PtIMe but complex failed react MeI. A comparison similar known complexes PPh (dppm) is made differences are attributed primarily lower steric hindrance dmpm.
