Review de Debut

Carbene ligands such as N-heterocyclic carbenes (NHC) and cyclic alkyl(amino)carbenes (cAAC) have been utilized for the synthesis of low-coordinated silicon compounds. The reduction of NHC- and cAAC-coordinated silicon tetrachlorides 2 and 7 gives unique silicon compounds 3-5 and 8-12, respectively. These studies should be important from the viewpoint of the isolation of the reactive small molecules such as Si2 and SiCl2. The properties of the central silicon fragments of NHC derivatives 3-5 and cAAC derivatives 8-12 are different from each other reflecting the stronger π-accepting character of cAAC compared with that of NHC.
