developed to synthesize ketones, esters, amides via the oxidative C−C bond cleavage of readily available alkyl aldehydes. Green and abundant molecular oxygen (O2) was used as the oxidant, and base metals (cobalt and copper) were used as the catalysts. This strategy can be extended to the one-pot synthesis of ketones from primary alcohols and α-ketoamides from aldehydes.
开发了一种广泛适用的方法,通过容易获得的烷基醛的氧化 C-C 键裂解来合成酮、酯、酰胺。绿色且丰富的分子氧(O 2)用作氧化剂,贱金属(钴和铜)用作催化剂。该策略可以扩展到由伯醇合成酮和由醛合成α-酮酰胺的一锅法。
