AbstractThe complex [OsTp(κ1-OCMe)2(PiPr3)]BF4 [Tp = hydridotris(pyrazolyl)borate] promotes the cleavage of both C(sp3)−C(sp2) bonds of benzylidenecyclopropane and 3-phenylpropylidenecyclopropane to yield the complexes [OsTp(═C═CHR)(η2-CH2═CH2)(PiPr3)]BF4 (R = Ph, CH2CH2Ph). The process is proposed to take place via metallacyclopropene intermediates stabilized by an ethylene chelation assistant. The driving force for the fragmentation is the high stability of the resulting ethylene−Os−vinylidene species.
