Abstract

The investigation of the PtCl2(diphosphine) + SnI2 and PtI2(diphosphine) + SnCl2 systems of catalytic importance (where diphosphines are 2,3-bis(diphenylphosphino)butane and 2,4-bis(diphenylphosphino)pentane) by NMR in solution has been carried out. Novel PtI(SnCl3)-(diphosphine) and PtI(SnCl2I)(diphosphine) complexes were formed as a consequence of the halide exchange reaction. The selective formation of PtI(SnCl3)[2,4-bis(diphenylphosphino)-pentane] was observed in the reaction of PtCl2[2,4-bis(diphenylphosphino)pentane] and 0.5 SnCl2 and 0.5 SnI2. PtI(SnCl3)[2,4-bis(diphenylphosphino)pentane], the first platinum complex which contains a chiral chelating diphosphine and SnCl3 ligand, was structurally characterized by X-ray diffraction.
