phosphinamides and aryl boronic acids with copper powder under an oxygen atmosphere is reported. This reaction proceeds efficiently to afford fully substituted unsymmetrical N-arylation phosphinamides at room temperature in excellent yields. Diverse unstable functional groups on the benzene ring of aryl boronic acids such as vinyl, formyl, acetyl, sulfonyl, acetylamino, cyano, nitro, and trifluoromethyl
据报道,在氧气气氛下,次膦酰胺和芳基硼酸与铜粉的螯合辅助C–N交叉偶联协议已被报道。该反应有效地进行,以优异的收率在室温下提供完全取代的不对称N-芳基次膦酰胺。可以容纳芳基硼酸的苯环上的各种不稳定官能团,例如乙烯基,甲酰基,乙酰基,磺酰基,乙酰氨基,氰基,硝基和三氟甲基。
