Unexpected Formation of Osmium Carbyne and Vinylidene Complexes from the Reaction of OsCl2(PPh3)3 with HC⋮CCMe3
摘要:
Treatment of OsCl2(PPh3)(3) with HC=CCMe3 produced a mixture of OsCl3(=CCH2CMe3)-(PPh3)(2) and OsCl(=C=CHCMe3)(C(C=CCMe3)=CHCMe3)(PPh3)(2). The structures of the new complexes have been confirmed by X-ray diffraction studies.
