Methylenecyclopropanes 1 bearing an electron withdrawing group react under palladium (0) catalysis with electron poor olefins to give skipped dienes 2. This reaction, which is believed to proceed via hydride transfer, highlights the fact that the reactivity of methylenecyclopropanes can be dramatically influenced by the nature of ring substituents.
