- N-Heterocyclic Carbene Complexes, Their Preparation And Use
-
Described are N-heterocyclic carbene complexes of the formula I, where n is 0 or 1, M is a metal atom containing group, R1 is selected from hydrogen alkyl, cycloalkyl, heterocycloalkyl, aryl and hetaryl, R2 is selected from hydrogen, alkyl, cycloalkyl, heterocycloalkyl, aryl and hetaryl, wherein R1 and R2 do not both stand for hydrogen. Furthermore, also described are methods for their preparation and their use as catalysts employed in a C—C, C—O, C—N or C—H bond formation reaction.
