Synthesis of 4- and 4,5-functionalized imidazol-2-ylidenes from a single 4,5-unsubstituted imidazol-2-ylidene

Mendoza-Espinosa, Daniel,Donnadieu, Bruno,Bertrand, Guy

supporting information; experimental part, p. 7264 - 7265 (2010/08/05)

Using the nucleophilicity of NHCs and a NHCs, as well as the leaving group ability of the former, the carbon-carbon double bond of imidazol-2-ylidenes can be readily mono- and difunctionalized. These results provide also a new light on the formation of abnormal carbene adducts from classical unsaturated NHCs.
