Aryl and alkylcarboxylate esters are converted into the corresponding α-hydroxy acids or α-alkoxyesters upon treatment with C6H5I(OAc)2 and base in the appropriate solvent.
在合适的溶剂中用C 6 H 5 I(OAc)2和碱处理后,芳基和烷基羧酸酯转化为相应的α-羟基酸或α-烷氧基酯。

2-Substituted oxirane-1,1-dicarbonitriles react with water, alcohols or phenol to give 2-substituted 2-hydroxyacetic acids, alkyl 2-alkoxyacetates and phenyl 2-phenoxyacetates, respectively. Reaction of 2-substituted oxirane-1,1-dicarbonitrile with thiophenol and a nucleophile, typically water ethanol or urea, gave 2-(phenylthio)acetic acids, ethyl 2-(phenylthio)acetates and N-aminocarbonyl-2-(phenylthio)acetamides.
