Treatment of Pt(PPh 3 ) 4 with N,N‐dimethylthiocarbamoyl chloride, Me 2 NC(=S)Cl, in dichloromethane at −20 °C processes the oxidative addition reaction to produce platinum complex [Pt(PPh 3 ) 2 (η 1 ‐SCNMe 2 )(Cl)], 2 with releasing two triphenylphosphine molecules. The 31 P{ 1 H} NMR spectra of complex 2 shows the dissociation of the triphenylphosphine ligand to form diplatinum complex [Pt(PPh 3 )Cl] 2 (μ,η 2 ‐SCNMe 2 ) 2 , 3 in which the two SCNMe 2 ligands coordinated through carbon to one metal center and bridging the other metal through sulfur. Complex 2 is characterized by X‐ray diffraction analysis.
