complexity, the cleavage and subsequent functionalization of the C(sp3)-C(sp3) single bond has received less attention than the CC bond formation reactions that have been extensively studied. Herein, by utilizing Cu/g-C3N4 nanometric semiconductor as a recyclable photocatalyst, an aerobic oxidative CC bond cleavage of aldehydes was developed with the promotion of amines under visible light irradiation.

由于其难度和复杂性,C(sp 3 )-C(sp 3 ) 单键的裂解和随后的功能化受到的关注少于已被广泛研究的 C C 键形成反应。在此,利用Cu/gC 3 N 4纳米半导体作为可回收光催化剂,制备了一种好氧氧化C在可见光照射下,随着胺的促进,醛的 C 键断裂得以发展。基于该反应,苯乙醛被选为高效的胺类甲酰化试剂。在蓝光照射下,室温下在 1 个大气压的氧气气氛中,各种胺类的甲酰胺收率均达到极佳。该方法为制备甲酰胺提供了一种实用、中性和温和的替代方法。
