摘要：

Two new stable compounds with a germanium-carbon double bond, the difluorenyl(fluorenylidene) germene 5 and the tert-butylfluorenyl(fluorenylidene)germene 11 have been synthesized by dehydrohalogenation of the corresponding halogenogermanes with tert-butyllithium. These germenes are stabilized both by steric effects of bulky groups such as fluorenyl or tert-butyl and by delocalization of electrons into the fluorene system.
