C(sp3)–C(sp3) cross-coupling of amines is described. Primary amines are converted to 1,2-dialkyldiazenes by treatment with O-nosylhydroxylamines in the presence of atmospheric oxygen. Denitrogenation of the diazenes with an iridium photocatalyst then forges the C–C bond. The substrate scope accommodates a broad latitude of functionality, including heteroaromatics and unprotected alcohols and acids.
描述了胺的 C(sp 3 )–C(sp 3 ) 交叉偶联方法。通过在大气氧存在下用O-对硝基羟胺处理,将伯胺转化为1,2-二烷基二氮烯。然后用铱光催化剂对二氮烯进行脱氮,形成 C-C 键。底物范围可容纳广泛的功能,包括杂芳族化合物和未受保护的醇和酸。
