Halogenogermenes: evidence for the formation of the chloro- or fluoro-germenes (Me5C5)(X)Ge[double bond, length as m-dash]CR2(CR2= fluorenylidene)

Abstract

The reaction of tert-butyllithium with dichloro- or difluoro-(pentamethylcyclopentadienyl)(fluorenyl)germane led to the corresponding stable lithio compounds which were characterized by reactions with various halides, trimethylsilyltriflate and methanol. The germenes (Me5C5)(X)Ge[double bond, length as m-dash]CR2(X = F or Cl, CR2= fluorenylidene) were obtained by the thermal defluorosilylation of Ge(C5Me5)F(X)[C(SiMe3)R2] and trapped in excellent yields by methanol, water or chloroform.
