A process for the preparation of 2-bromoalkyl esters and vicinal glycol esters which comprises thermally decomposing at temperatures of from 100.degree. C. to 200.degree. C. an organic bromoalkyl tellurium compound selected from 2-bromoalkyltellurium tribromide or bis(2-bromoalkyl)tellurium dibromide, wherein the alkyl group is ethyl, propyl or butyl, in a carboxylic acid having from 1 to 4 carbon atoms which is employed as solvent as well as to supply the ester moiety to the esters produced. The esters may be converted to the respective glycol with water or an aqueous base.
一种制备2-溴烷基酯和邻二醇酯的过程,包括在100°C至200°C的温度下热分解有机溴烷基碲化物,所述有机溴烷基碲化物选自2-溴烷基碲三溴化物或双(2-溴烷基)碲二溴化物,其中烷基为乙基、丙基或丁基,所述过程在1至4个碳原子的羧酸中进行,该羧酸既作为溶剂又为产生酯基的酯提供物。所述酯可以通过水或水溶性碱转化为相应的邻二醇酯。
