2-Trimethylsilylmethylenecyclopropane (3) was synthesized by reaction of lithio methylenecyclopropane with TMSCl.The lithium salt of 3 reacts with some electrophiles by α- or γ-attack depending on the nature of the electrophile.Whereas alkenylbromides 8 and 9 or alkinylbromide 10 give exclusively α-attack, benzaldehyde reacts with γ-alkylation.
