Dimesitylneopentylgermene, a new stable germene
Couret,Escudié,Delpon-Lacaze,Satgé
, p. 3176 - 3177 (2008/10/08)
The dimesitylenopentylgermene Mes2Ge= CHCH2-t-Bu (3) was synthesized in high yield by an addition-elimination reaction between dimesitylvinylfluorogermane and tert-butyllithium. It is stable at room temperature and is highly reactive toward etectrophilic and nucleophilic reagents.
