The room temperature addition of electrophilic alkyl halide reagents (RX = MeI, EtI and PhCH2Br) to complex [Pt(ppy)(η1-S-Spy)(PPh3)], 1a, in which ppyH = 2-phenylpyridine and pySH = pyridine-2-thiol, resulted in a rapid carbon-sulfur (C-S) bond reductive coupling to produce alkyl sulfides and corresponding halide complexes [Pt(ppy)(PPh3)X], X = I (2a) and Br (2b). A mechanism for this C-S bond formation reaction was suggested based on 1H and 31P {1H} NMR spectroscopic analyses. In the suggested mechanism, the reaction proceeded through a binuclear intermediate complex [{Pt(ppy)(PPh3)}2(μ2-Spy)]I, 3-I, which was separately synthesized by another counter anion (PF6) and it was fully characterized by multinuclear NMR spectroscopy and single X-ray crystallography. Also, density functional theory (DFT) calculations were used to theoretically assess the structures of intermediates and transition states in this bond formation reaction.
