摘要: A convenient route to polycyclic compounds incorporating a silicon atom at ring junction has been developed. Benzosilacyclobutenes tethered alkynes or alkenes undergo intramolecular cycloadditions in the presence of CpCo(CO)2. The incorporation CpCo(CO) moiety into benzosilacyclobutene framework occurs regioselectively Ar−Si bond silacycle give 1-cobalta-2-silacyclopentenes. On basis DFT/B3LYP calculations, nonadiabatic mechanism involving changes spin state is proposed.
