1,2-dizinc reagents can be prepared by an indium-catalyzed insertion of zinc powder into aromatic 1,2-dibromides or 1-bromo-2-triflates. These 1,2-dimetallics undergo Cu- or Pd-catalyzed acylations, allylations, or cross couplings. A variety of functionalized 1,2-dizinc reagents can be prepared by an indium-catalyzed insertion of zinc powder into aromatic 1,2-dibromides or 1-bromo-2-triflates. These
摘要 可以通过铟催化将锌粉插入芳族1,2-二溴化物或1-溴-2-三氟甲磺酸酯中来制备各种功能化的1,2-二嗪试剂。这些1,2-二金属化合物经过Cu或Pd催化的酰化,烯丙基化或交叉偶联。 可以通过铟催化将锌粉插入芳族1,2-二溴化物或1-溴-2-三氟甲磺酸酯中来制备各种功能化的1,2-二嗪试剂。这些1,2-二金属化合物经过Cu或Pd催化的酰化,烯丙基化或交叉偶联。
