We report herein on the nickel-catalyzed methylation of arylphosphines using AlMe3 via the cleavage of unactivated C(aryl)–P bonds. This reaction allows for the direct, catalytic substitution of an aryl group on a phosphorus center with a methyl group. This catalytic methylation can proceed, when phosphine oxides and sulfides are used as a substrate.
我们在此报告了使用 AlMe 3 通过未活化的 C(芳基)-P 键的裂解进行镍催化的芳基膦甲基化。该反应允许用甲基直接催化取代磷中心上的芳基。当使用氧化膦和硫化物作为底物时,可以进行这种催化甲基化。
