A highly efficient protocol for the Pd-catalyzed regioselective Heck arylation of the electron-richolefin N-acyl-N-vinylamine with aryl halides has been developed. In the presence of hydrogen-bonddonor [H2NiPr2][BF4] as an additive, this proceeds smoothly in isopropanol to afford exclusively the branched products in high yields.
已经开发出用于富电子的烯烃N-酰基-N-乙烯基胺与芳基卤化物的Pd催化区域选择性Heck芳基化的高效方案。在存在氢键供体[H 2 N i Pr 2 ] [BF 4 ]作为添加剂的情况下,该过程在异丙醇中顺利进行,从而以高收率独家提供支链产物。
