摘要：
Treatment of Pt(PPh3)(4) with N,N-dimethylthiocarbamoyl chloride, Me2NC(=S)Cl, in dichloromethane at -20 degreesC processes the oxidative addition reaction to produce platinum complex [Pt(PPh3)(2)(eta(1)-SCNMe2)(Cl)], 2 with releasing two triphenylphosphine molecules. The P-31 (H-1) NMR spectra of complex 2 shows the dissociation of the triphenylphosphine ligand to form diplatinum complex [Pt(PPh3)Cl](2)(mu,eta(2)SCNMe(2))(2), 3 in which the two SCNMe2 ligands coordinated through carbon to one metal center and bridging the other metal through sulfur. Complex 2 is characterized by X-ray diffraction analysis.
