μ-alkylidyne and μ-alkylidene complexes from a bridging side-on vinylidene sulfur-rich dimolybdenum precursor

Abstract : The reaction of the μ-vinylidene sulfur-rich dimolybdenum complexes with μ-alkyldyne derivatives was investigated. The reaction resulted in good yield, and when treated with a HBF4·Et2O based complex it readily converted into μ-alkyldene species. The α-agostic interactions in the μ-alkyldene complexes were revealed through NMR spectroscopy.
