New coumarins and new 2-(2′,2′-dichlorovinyl) phenols have been prepared by cathodic reduction under potentiostatic conditions of trichloroacetyl esters of o-hydroxyketones and o-hydroxyaldehydes in aprotic media. Electroreductions of trichloroacetyl esters of α-hydroxy-1,4-naphthoquinone, 3-hydroxy-2-methyl-4-pyrone, methyl salicylate and benzoin have also been investigated.
通过在非质子介质中邻羟基酮和邻羟基醛的三氯乙酰基酯的恒电位条件下,通过阴极还原,制备了新的香豆素和新的2-(2',2'-二氯乙烯基)苯酚。还研究了α-羟基-1,4-萘醌,3-羟基-2-甲基-4-吡喃酮,水杨酸甲酯和安息香的三氯乙酰基酯的电还原。
