Abstract
A new type of Si(II): A novel silylene stabilized by a Cp* and an imidazolin-2-iminato ligand has been prepared using two different methods (see scheme). The X-ray crystallographic structure shows that the silicon(II) center is coordinated to an ?2-Cp* ligand and the nitrogen atom of an imidazolin-2-iminato ligand. This silylene easily reacts with B(C6F5)3 to give a stable borane adduct having a zwitterionic resonance structure.
