We report a highly efficient ring-opening reaction of vinylcyclopropanes by boronic acids in water, using palladium nanoparticles formed from Pd(OAc)2 under ligandless conditions. Unsubstituted vinylcyclopropanes provide linear addition products with high selectivity, while a switch in regioselectivity to branched products is observed for aryl-substituted vinylcyclopropanes.
我们报告了在无配体条件下使用由Pd(OAc)2形成的钯纳米粒子,水中硼酸对乙烯基环丙烷的高效开环反应。未取代的乙烯基环丙烷可提供具有高选择性的线性加成产物,而对于芳基取代的乙烯基环丙烷,可观察到区域选择性转变为支链产物。
