ResumoThe structure of the ring insertion product 1b obtained from the reaction of [Pt(dppm)(CH2Cl2] (dppm = Ph2PCH2PPh2) with triphenylphosphine has been confirmed by X-ray crystallography of the hexafluorophosphate salt. The bis-chelate complex (IIIa) has been isolated from the reaction of [Pt(dppm)(CH2Cl2] (II) with diphenylphosphine in dichloromethane. Iodination of Ib leads to selective cleavage of the chloromethyl group, and subsequent iodide abstraction with silver ion gives a solvated cation (V). The structures of the hexafluorophosphate salts of the bis-chelate IIIb and of the solvated cation V have been determined by X-ray diffraction.
