Abstract
The synthesis, structure, and dynamic behavior of [W(CPhCHCMe2)Br2(CO)2L], 2, are reported. A structural comparison with [W(CPhCHCHMe)Br2(CO)2L], 1, is made. The introduction of an additional methyl substituent at the vinyl group in 2 causes a significant lengthening of the metal-vinyl bond. Simple electronic considerations suggest that the weakness of the metal-vinyl interaction may be explained by the absence of π-backbonding. The presence of an additional methyl substituent in the vinylcarbene ligand also affects the reactivity of complex 2.
