products, liberating hydrogen gas, is reported. The reaction is catalyzed by a pincer complex of earth-abundant manganese in the presence of catalytic base, without any hydrogen acceptor or oxidant. Mechanistic insight indicates that a dearomatized complex is the actual catalyst, and indeed this independently prepared dearomatized complex catalyzes the reaction under neutral conditions.
据报道,伯醇的贱金属催化脱氢交叉偶联形成交叉酯为主要产物,释放出氢气。该反应是在没有任何氢受体或氧化剂的情况下,在催化剂碱的存在下,由富含地球的锰的夹杂物络合物催化的。机械学的见解表明脱芳香化的络合物是实际的催化剂,并且实际上,这种独立制备的脱芳香化的络合物在中性条件下催化了反应。
