Bis-hydrocarbyl Platinum(II) Ambiphilic Ligand Complexes: Alkyl–Aryl Exchange between Platinum and Boron

Reaction of TXPB (2,7-di-tert-butyl-5-diphenylboryl-4-diphenylphosphino-9,9-dimethylthioxanthene) with [PtMe2(COD)] (COD = 1,5-cyclooctadiene) yielded [PtMePh­(TXPB′)] (1; TXPB′ = 2,7-di-tert-butyl-5-methylphenylboryl-4-diphenylphosphino-9,9-dimethylthioxanthene), presumably via undetected [PtMe2(TXPB)]. The ambiphilic ligand in 1 is κ2 PS-coordinated, and the trigonal plane of the borane is oriented approximately parallel to the square plane …
