Abstract

In contrast to carbene complexes of groups 5I and 62 metals, which have been extensively studied, knowledge of carbene complexes of group 4 metals is limited to one observed Zr species3 and several postulated Ti intermediate^.^,^ This relative lack of information may be due to limitations in synthetic techniques heretofore available and not to any inherent instability of members of this class.
