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-1,3-butanediols or 2-sec(or -tert)alkyl-1,3-butanediol diacetates.
