diphenylcarbene and phenylmethoxycarbene complexes of pentacarbonyltungsten. Both the cycloheptatrienylidene and cyclopropenylidene complexes are poorer π-acceptors than the other carbene complexes. Furthermore there is some evidence that cyclopropenylidene is a poorer acceptor than cycloheptatrienylidene although this is not conclusive. Both of the cyclopropenylidene complexes show greater thermal stability
