Alcohols are among the most abundant and commonly used organic feedstock in industrial processes and academic research. The first tandem O–H insertion/[1,3]-alkyl shift reaction reported is between benzylic alcohols and rhodium azavinyl carbenoids derived from N-sulfonyl-1,2,3-triazoles, which provides a strategically novel way of cleaving C–OH bonds and forming C–C bonds. The substrate scope is broad
酒精是工业过程和学术研究中最丰富,最常用的有机原料之一。报道的第一个串联的O–H插入/ [1,3]-烷基转移反应是在苄醇与衍生自N-磺酰基-1,2,3-三唑的氮杂氮杂乙烯基铑类化合物之间进行的,这提供了一种策略性地裂解C-的新方法。 OH键并形成C–C键。底物的范围很广,能够覆盖1°-,2°-和3°-苄醇。而且,它构成了构造α-氨基酮的新的有力的合成方法。机理研究表明,氧鎓叶立德的[1,3]-烷基移位是C-OH键断裂的原因。
