Visible-light-promoted α-methoxymethylation and aminomethylation of ketones using methanol as a sustainable C1 source have been developed. With rose bengal as the photosensitizer and air as the green oxidant, the methoxymethylation reactions proceeded smoothly under visible light irradiation at ambient temperature. Additionally, a one-pot one-step α-aminomethylation of ketones was achieved by adding
已开发出使用
甲醇作为可持续 C1 源的可见光促进的 α-甲氧基甲基化和酮的
氨基甲基化。以玫瑰红为光敏剂,空气为绿色氧化剂,在常温可见光照射下,甲氧基甲基化反应顺利进行。此外,通过添加 N- 亲核试剂实现了酮的一锅一步 α-
氨基甲基化。初步机理研究表明,该反应主要通过自由基途径进行。
