and efficient visible light induced Meerwein hydration reaction of alkenes in aqueous medium using mpg-C3N4 as a recyclabe photocatalyst has been disclosed. This protocol provides a direct approach for the preparation of racemic alcohols via a free radical mechanism. Water acted as both a solvent and a reagent without any additives or co-solvents. The metal-free heterogeneous semiconductor is found
已经公开了使用mpg-C 3 N 4作为可回收的光催化剂,绿色和有效的可见光诱导的水性介质中烯烃的Meerwein水合反应。该协议提供了一种通过自由基机制制备外消旋醇的直接方法。在没有任何添加剂或助溶剂的情况下,水既充当溶剂又充当试剂。发现不含金属的异质半导体至少可以完全回收5次,而活性没有任何显着降低。Meerwein水合反应具有出色的底物范围,并以中等至高收率提供了所需的产物。此外,该反应可以在太阳光照射下进行,并且可用于大规模反应,并具有令人满意的结果。
