Reactivity of Diaryl Bismuth Cations toward a Platinum(0) Complex: Oxidative Aryl Transfer.

ABSTRACT: Reactions of three aryl-substituted bismuth cations, [BiPh₂(SbF₆)], [BiMes₂(SbF₆)], and [BiDipp₂(SbF₆)], with the Pt⁰ complex Pt-(PCy₃)₂ have been investigated (Mes = 2,4,6-trimethyl-phenyl; Dipp = 2,6-di-iso-propyl-phenyl; Cy = cyclohexyl). Unexpectedly, and in contrast with the reactivity of the recently reported methyl analogue [BiMe₂(SbF₆)], the formation of isolable metal-only Lewis pairs [(Cy₃P)₂Pt→BiAr₂(SbF₆)] is not observed (Ar = aryl). Instead, an unprecedented bismuth-to-platinum oxidative aryl transfer is witnessed to give the Pt^II complexes [PtAr-(PCy₃)₂(SbF₆)], al
