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.
我们报道了在无配体条件下由醋酸钯形成的钯纳米颗粒催化,硼酸在水中使乙烯基环丙烷发生的高效开环反应。未取代的乙烯基环丙烷能以高选择性提供线性加成产物,而对于芳基取代的乙烯基环丙烷,区域选择性则转变为支链产物。
