Synthesis of Chloro Boryl Complexes by Oxidative Addition of B–Cl Bonds

Some platinum boryl complexes of the type trans‐[(Cy₃P)₂Pt(Cl){B(Cl)R}] ( 1 : R = NMe₂, 2 : R = Mes, 3 : R = tBu) were synthesized by oxidative addition of the corresponding dichloroboranes to [Pt(PCy₃)₂]. All the compounds were characterized by multinuclear NMR spectroscopy in solution. Furthermore, a single crystal analysis was acquired from 2 , that confirms the strong trans‐influence of this boryl ligand.
