The preparation of metallacycle 1 by the addition of 3,3-dimethylcyclopropene to precursors of Cp2Ti=CH2 (Cp = η5-C5H5) is described. Reaction of 1 with benzophenone affords 3,3-dimethyl-1,1-diphenyl-1,4-pentadiene as the only organic product. When phosphines PMeR2 (R = Me, Ph) are added to 1, the phosphine adducts (PMeR2)Cp2Ti=CHCMe2CHCH2 (2) are obtained. Reaction with dimethylaluminum chloride affords a heterobimetallic alkylidene complex, Cp2TiCH(CMe2CHCH2)AlMe2Cl (3). The observed reactivity of 1 is consistent with productive cleavage of the metal-containing ring to Cp2Ti=CHC(Me2)2CHCH2 .
