Cyclopropene reacts with Mo(CO)2(S2CNR2)2, Mo(CO)2(S2PR2)2, W(CO)3(S2CNR2)2, and W(CO)2(PPh3)(S2CNR2)2 to yield new complexes that are best formulated as M(CO)(C3H4CO)(BB)2 (M = Mo, W). Analogous products form when 1-methylcyclopropene reacts with W(CO)3(S2CNR2)2. Infrared, 1H NMR, and 13C NMR spectroscopic techniques have been used to probe the mode of attachment of the newly formed vinylketone ligand, C2H3RCO (R = H, CH3), which evidently results from cyclopropene ring opening and CO insertion.
