Abstract

Acrylates or methacrylates I ##STR1## (A and B=C.sub.2 -C.sub.5 -alkylene, R.sup.1 =H, CH.sub.3) are prepared by reacting an acrylate or methacrylate II ##STR2## (R.sup.2 =C.sub.1 -C.sub.4 -alkyl) with a heterocycle III ##STR3## in the presence of titanium alcoholates chelate compounds of the metals titanium, zirconium, iron and zinc with 1,3-dicarbonyl compounds.
