Angew.Chem.Int.Ed.2013,52,11303~11307碳-碳(C—C)键断裂是一类非常重要的有机化学反应,但是由于C—C键内在惰性,选择性C—C键活化/官能团化仍然是有机化学极具挑战性的研究课题.酮是一大类易得的有机化合物,酮羰基与α-碳的氧化性断裂能够实现多种有用的官能团转化,但是由于醛类化合物极易被氧化成羧酸,所以从酮直接转化成醛的文献报道比较少,并且一 Angew.Chem.Int.Ed.2013,52,11303-11307 Carbon-carbon (C-C) bond cleavage is a very important class of organic chemical reactions, but due to the inherent inertness of the C-C bond, the optional C-C bond Activation / Functionalization is still a very challenging topic in organic chemistry.Ketones are a large group of readily available organic compounds and the oxidative cleavage of keto carbonyls with α-carbon enables many useful functional group conversions, but aldehydes The compounds are easily oxidized to carboxylic acids, so there is relatively little literature reported to convert ketones directly to aldehydes, and one
