Methylene cyclopropanes 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 methylene cyclopropanes can be dramatically influenced by the nature of ring substituents.
带有吸电子基团的亚甲基环丙烷1在钯(0)催化下与贫电子的烯烃反应,生成跳过的二烯2。据信该反应是通过氢化物转移进行的,这一事实突出了以下事实:亚甲基环丙烷的反应性可受到环取代基的性质的显着影响。
