The direct esterification of aldehydes and alcohols was carried out with pyridinium hydrobromide perbromide in water at room temperature. A variety of aldehydes were converted to respective ester derivatives with alcoholssuch as methanol, 1,2-ethanediol, 1,3-propanediol. Further, a variety of aliphatic alcohols were also converted to the corresponding Tishchenko-like dimeric esters in good yields under
醛和醇的直接酯化反应在室温下用过溴化氢溴化吡啶鎓在水中进行。多种醛与醇例如甲醇、1,2-乙二醇、1,3-丙二醇转化为各自的酯衍生物。此外,在相同的反应条件下,各种脂肪醇也以良好的产率转化为相应的 Tishchenko 样二聚酯。
