Organo-silyl and -germyl complexes of platinum. Part II

Oxidative Addition of Silicon−Halogen Bonds to Platinum(0) Complexes and Reactivities of the Resulting Silylplatinum Species

“…For the reactivities of halosilanes toward palladium(0) or platinum(0) complexes, it was reported that Me 3 SiCl reacted with 1b or Pd(PPh 3 ) 4 to provide a disilane (Me 3 SiSiMe 3 ) along with the corresponding metal dichloride (PtCl 2 (dppe) or PdCl 2 (PPh 3 ) 2 ). The disilane might be formed via sequential reactions of the 2 equiv of the Me 3 Si−Cl bond with the metal species.…”

Cis and Trans Isomers of Pt(SiHAr2)2(PR3)2(R = Me, Et) in the Solid State and in Solutions

“…Platinum complexes with organosilyl ligands − have been widely studied because the complexes are often involved as crucial intermediates in Pt complex catalyzed synthetic reactions such as hydrosilylation of alkenes, bissilylation of alkenes and dienes, and dehydrocoupling of organosilanes to form Si−Si or Si−C bonds . Most of the mononuclear bis(organosilyl)platinum complexes and alkyl- or hydrido(organosilyl)platinum(II) complexes bearing two phosphine ligands favor cis structure of the square-planar coordination.…”

Silyl Migration from Iron to Platinum in dppm-Bridged Bimetallic Complexes

“…To achieve the usual 18-electron count on iron and 16-electron count for the Pt(II) center with d 8 configuration, the presence of an additional metal−metal bond is not required for 3 . The ligand arrangement around the platinum center of 3 corresponds therefore to that reported for a range of mononuclear Pt(II) complexes of the type trans -[PtCl(SiR 3 )(PR 3 ) 2 ] . Considering a possible rotation of the platinum square plane about an axis passing through the Fe and Pt atoms, the degree of twisting of the dppm ligands cannot be stated in the absence of a crystal structure.…”
