heteroatoms to give aryl aldehydes is reported. The unstrained carbon–carbon single bond cleavage reaction uses ambient air as the sole oxidant, proceeds efficiently at room temperature, and allows for exceptional functional-group tolerance, which addresses the long-standing challenges of current C–C bond cleavage/functionalization. Notably, the method enables rapid late-stage oxidation of complex bioactive
据报道,在没有杂原子的帮助下,烯丙基芳烃的一般和选择性铁催化烯丙基的C–C(乙烯基)σ键裂解可得到芳基醛。无应变的碳-碳单键裂解反应使用环境空气作为唯一氧化剂,在室温下有效进行,并具有出色的官能团耐受性,从而解决了当前C-C键裂解/官能化的长期挑战。值得注意的是,该方法能够使复杂的生物活性分子快速后期氧化,并可用于加速从容易获得的化学原料中合成天然产物(香兰素和葡糖香兰素)。
