Abstract

The thermal reactions of an overcrowded germacyclopropabenzene with group 6 metal hexacarbonyl complexes [M(CO)6] (M = Cr, Mo and W) resulted in the formation of novel Fischer-type carbene complexes via the insertion reaction of a C=O group to the Ge-C bond. By contrast, the germacyclopropabenzene reacts with [Co2(CO)8] to give a germanium analog of benzocyclobutanone via the insertion reaction of a CO unit into the germacyclopropane ring. The reaction of the germacyclopropabenzene with [Mn2(CO)10] resulted in the formation of the intramolecular cyclization product accompanying the migration of a trimethylsilyl group, i.e. a cyclobutabenzene derivative.
