Efficient ruthenium-catalysed S-S, S-Si and S-B bond forming reactions

[RuCl(PPh3)(2)(3-phenylindenyl)] (1) has been shown to be an efficient catalyst in thiol dehydrogenative coupling to give disulfides. Moreover, an efficient procedure for the preparation of silylthioethers and thioboranes is presented. Complex 1 demonstrated a great ability to catalyse the coupling of thiols with silanes and boranes under mild conditions with excellent results (turnover number up to 200).
