Thermal reactions of an overcrowded germacyclopropabenzene with group 6 metal hexacarbonyl complexes [M(CO)6](M = Cr, Mo, and W): a novel mode of CO insertion leading to the formation of cyclic germoxycarbene metal complexes.

Abstract

Thermal reactions of an overcrowded germacyclopropabenzene with hexacarbonyl complexes of group 6 metals resulted in the formation of the corresponding cyclic germoxycarbene complexes, i.e., 1,2-oxagermolan-5-ylidene pentacarbonyl metal complexes, via a novel mode of CO insertion reaction toward cyclopropabenzene derivatives.
