Economical and efficient processes for producing an alpha , beta -unsaturated carboxylic acid heterocycle-inserted ester and an alpha , beta -unsaturated carboxylic acid polyheteroalkylene ester as well as a catalyst suited for use in economically and efficiently producing an alpha , beta -unsaturated carboxylic acid ester are provided. The invention provides (1) a process for producing an alpha , beta -unsaturated carboxylic acid ester which comprises reacting an alpha , beta -unsaturated carboxylic acid ester with a heterocyclic compound, (2) a process for producing an alpha , beta -unsaturated carboxylic acid ester which comprises reacting an alpha , beta -unsaturated carboxylic acid with a heterocyclic compound in the presence of a polymerization inhibitor and a metal oxide catalyst, and (3) a catalyst for the production of an alpha , beta -unsaturated carboxylic acid ester comprising a metal oxide.s fo |
