The Hammett reaction constant for the reaction of the terminal phosphinidene complex [Ph-P=W-(CO)5], as generated from the appropriate 7-phosphanorbornadiene complex, toward styrenes is reported and compared to those of free carbenes. The mild electrophilicity supports the unencumbered carbene-like nature of the phosphinidene complex and suggests a concerted addition to olefins with a slightly polar transition state.
