Abstract

Recently, Wiberg and co-workers reported the preparation of TTF analogue with a disilane backbone, obtained from the reaction of the isolable disilene with carbon disulfide. They suggested that S-heterocyclic carbene intermediate plays the important role in the process of the generation of TTF analogue. Meanwhile, heterocyclic carbenes have attracted special attention as a spin source, ligand, catalyst and so forth, due to their unique coordination properties. Recently, we have reported the generation of a tetracyclosilene by the photolysis of the anti-dodecaalyltricyclo[4.2.0.0^2,5]octasilane. Herein we report the generation of S-heterocyclic carbene with a cyclotetrasilane backbone by [2+3] cycloaddition of tetracyclosilene with carbon disulfide. The carbene has been confirmed by trapping it with C₆₀ as a chemical probe. The structural determination of the obtained C₆₀ derivative has been performed by spectroscopic and X-ray crystallographic analysis.
