Group 10 Transition-Metal Complexes of an Ambiphilic PSB-Ligand: Investigations into η3(BCC)-Triarylborane Coordination

Reaction of 2,7-di-tert-butyl-5-diphenylboryl-4-diphenylphosphino-9,9-dimethylthioxanthene (TXPB) with [PdCl2(COD)] resulted in the formation of [PdCl(μ-Cl)(TXPB)] (3), which can be reduced in a stepwise fashion, forming [Pd(TXPB)] (2) via [{PdI(μ-Cl)(TXPB)}2] (4). Dinuclear 4 could also be prepared through a comproportionation reaction of palladium(II) complex [PdCl(μ-Cl)(TXPB)] (3) with either [Pd(TXPB)] (2) or [Pd(dba)(TXPB)] (5). In …
