B–H activation and H–H formation: two consecutive heterolytic processes on an osmium–hydrogensulfide bond†‡
Abstract
Heterolytic B–H activation and H–H formation on an Os–SH bond give borylthiolate-dihydrogen derivatives. These species exchange borylthiol by borane to afford σ-borane derivatives or release H2 and undergo a hydride-boryl exchange to yield boryl-hydrogensulfide complexes depending on the boryl group bonded to the sulfur atom.
