PURPOSE: To obtain this compound from an easily handleable safe raw material by reacting an acrylic acid alkyl ester derivative with a diketene in the presence of a t-alkylamine or a metal alkoxide.
CONSTITUTION: The compound of formula III can be produced by reacting a 2-(1-hydroxymethyl)acrylic acid ester of formula I (R is an alkyl such as methyl, ethyl, n-propyl, i-propyl and n-butyl) with the diketene of formula II in the presence of a t-alkylamine (e.g. 1,4-diazabicyclo[2,2,2]octane) or a metal alkoxide (e.g. sodium ethoxide) preferably in a solvent (e.g. chloroform) at 20-180°C). The compound of formula III is useful as a raw material for polymer for plastics, paint, tacky adhesive, paper-processing agent, polymer modifier, ion exchange resin, etc.
