Abstract

Abstract The rearrangement of ethoxyethynyl-carbinols into unsaturated esters was investigated in acidic aqueous solution. The reaction is general acid catalyzed and β- hydroxy esters are by-products. There exists a simple relation between the ratio of β-hydroxy ester to unsaturated ester and the concentration of hydroxyl and acetate ions. The two products are formed in a common rate determining step, which is a proton addition to the β ...
