    • 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.
    • 本发明涉及以含有直接金属 - 氮键的锡或锌化合物为特征的新型催化剂。 新型催化剂衍生自伯胺或仲胺如烷基胺,杂环胺,芳族胺等。胺与锡化合物如氯化锡,溴化锡,氧化锡或 一种锡醇盐。 或者,胺可以与卤化锌,烷氧基锌或有机锌化合物反应。 在本发明的另一方面,新型催化剂用于催化丙烯酸酯或甲基丙烯酸酯与胺的反应,以便以高产率和高选择性制备N-取代的丙烯酰胺或甲基丙烯酰胺。
