Arylhydrogermyllithiums: synthese et applications

Castel, Annie,Riviere, Pierre,Satge, Jacques,Ko, Young-Hoon

, p. C1 - C4 (1988)

New organohydrogermyllithium are prepared in good yields from hydrogermolysis reactions with t-butyllithium in THF.Alkylation and germylation of the germanium-lithium bond in these compounds are efficient reactions and a convenient way for synthesis of organohydropolygermanes.These reagents are also useful for the formation of unknown hydrogermylmagnesium compounds.
