A visible‐light‐mediated α‐hydroxymethylation of ketones using methanol as the hydroxymethylating reagent has been developed. Using 1 mol% rose bengal as the photosensitizer and air as the green oxidant, the reactions proceeded smoothly at room temperature. Experimental studies indicate the reaction proceeded via a radical pathway.
已经开发出使用甲醇作为羟甲基化试剂的酮的可见光介导的α-羟甲基化方法。使用1mol%的孟加拉红作为光敏剂,并使用空气作为绿色氧化剂,该反应在室温下顺利进行。实验研究表明反应是通过自由基途径进行的。
