It was found that β-ketoesters were directly transformed to the corresponding α-hydroxymalonic esters, tartronic esters, with molecular oxygen catalyzed by calcium iodide under visible light irradiation from fluorescent lamp. This reaction includes tandem oxidation/rearrangement and has received much attention from the viewpoint of reduction of energy consumption, labor, and solvents.
发现在荧光灯的可见光照射下,
碘化钙催化的分子氧将β-
酮酸酯直接转化为相应的α-羟基
丙二酸酯,tartronic酯。该反应包括串联氧化/重排,并且从减少能耗,劳力和溶剂的角度出发已经引起了广泛的关注。
