A Sound Sequence to Triphenylphosphino Dibromoplatinum(II) Complexes - Solvothermal Preparation of trans-[PtBr(mu-Br)(PPh3)](2)

摘要

A sound synthetic procedure for the preparation of trans-[PtBr(mu-Br)(PPh3)](2) is described. The species was fully characterized and used to obtain [PtBr2(PPh3)(L)] complexes (L = DMSO, p-toluidine, pyridine) by a bridge-splitting reaction. All products were fully characterized by NMR spectroscopy, together with cis-[PtBr2(PPh3)(NCCH3)], obtained as an intermediate in the synthesis of the dinuclear precursor. Cis-[PtBr2(PPh3)(NCCH3)] was also studied by X-ray diffraction.
