Zusammenfassung:PURPOSE:To obtain this compound from an easily handleable safe raw material by decarboxylating an acrylic acid alkyl ester derivative in the presence of a t-alkylamine or a metal alkoxide. CONSTITUTION:The compound of formula II can be produced by decarboxylating a 2-(1-acetoacetoxymethyl)acrylic acid alkyl ester of formula I (R is an alkyl such as methyl, ethyl, n-propyl, i-propyl and n-butyl) 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 deg.C. The compound of formula II is useful as a raw material for polymer for plastics, paint, tacky adhesive, paper-processing agent, polymer modifier, ion exchange resin, etc.
