transformation took place readily under the oxidative conditions, and plenty of N-alkylated (methylated) amides (30 examples) were successfully furnished in high efficiency (up to 92% yields). Dicumyl peroxide was considered to act either as the oxidant for the alkylation reaction or as methyl donator for the methylation protocol.
本文证明了针对N-烷基或N-甲基膦酰胺和次膦酰胺的有效且实用的CuI催化方法。该转化在氧化条件下容易发生,并且成功地高效地提供了许多N-烷基化(甲基化)酰胺(30个实例)(产率高达92%)。过氧化二枯基被认为是充当烷基化反应的氧化剂或充当甲基化方案的甲基供体。
