Under moderate conditions aldoenol esters react with HAl(i-C4H9)2 to afford organoaluminium compounds, which upon hydrolysis yield 1,3-diols and on acetolysis form 1,3-diacetates. The diacetates are obtained in about 50% yields (based on enol ester) by distillation. Vinyl esters are converted to linear 1,3-diols or 1,3-diacetates, whereas enol acetates of higher aldehydes give 2-sec(or -tert)alkyl-1
在中等条件下,醛烯醇酯与HAl(iC 4 H 9)2反应,得到有机铝化合物,其水解后生成1,3-二醇,并在乙酰分解时生成1,3-二乙酸酯。通过蒸馏以约50%的产率(基于烯醇酯)获得二乙酸酯。乙烯基酯被转化为直链的1,3-二醇或1,3-二乙酸酯,而高级醛的烯醇乙酸酯得到2-仲(或-叔)烷基-1,3-丁二醇或2-仲(或-叔)烷基-1,3-丁二醇二乙酸酯。
