内 容 简 介：The preparation, structure and electronic properties of novel families of stable carbenes, including six-membered cyclic (alkyl)(amino)carbenes, bicyclic (alkyl)(amino)carbenes, and even mono-substituted carbenes  will be discussed. It will be shown that the peculiar electronic and steric properties of these carbenes (CAACs) allow for the stabilization of unusual diamagnetic and paramagnetic transition metals and main group element species. We will also show that these carbenes allow for the isolation of catalytically active complexes, which were supposed to be onlytransient intermediates. Among them, bis(copper) complexes  involved in the very popular CuAAC reaction (Click Chemistry) will be discussed. We will show that this discovery allows for the development of novel catalytic transformations.
