N-heterocylic and mesoionic carbene complexes of the group 4 metals

subject

description

International audience; N-heterocyclic carbene (NHC) complexes of group 4 metals have been far less studied than their late metal counterparts. However, the field has been explored for over 25 years, and there is now a much clearer understanding of the metal-NHC interaction. Some exceptionally robust and active catalysts have been reported for a number of group 4 metal-catalyzed reactions, and recent developments suggest that NHCs are well-suited to enable the isolation of otherwise difficult to tame species, such as low-valent complexes.
