Abstract

Primary and secondary alcohols react with vinyl or isopropenyl acetate at room temperature in the presence of Y₅(OiPr)₁₃O as catalyst to give the corresponding esters. In selected cases, the yttrium catalyst promotes a selective O-acylation of amino alcohols without the formation of the amide.
