ABSTRACT:
This invention is directed to novel catalysts characterized as compounds of tin or zinc containing a direct metal-nitrogen bond. The novel catalysts are derived from a primary or secondary amine such as an alkyl amine, a heterocyclic amine, an aromatic amine, etc. The amine is reacted with a tin compound such as a tin chloride, a tin bromide, a tin oxide, or a tin alkoxide. Alternatively, the amine may be reacted with a zinc halide, a zinc alkoxide or an organozinc compound.
In another aspect of the present invention, the novel catalysts are used to catalyze the reaction of an acrylate or methacrylate ester with an amine in order to prepare N-substituted acrylamides or methacrylamides in good yield and with high selectivity.
