The unprecedented C(sp2)–H functionalization of ethylidenemalonate with internal alkynes was discovered, leading to substituted vinylcyclopentanes as trans,trans-isomers (dr > 15 : 1). The experiment with deuterated ethylidenemalonate showed that the formation of substituted vinylcyclopentane is accompanied by a 1,2-hydride shift and mono-γ-C–H insertion into the internal alkyne.
