Mechanism Of The Reaction

According to the results of a quantum chemical study in the framework of the electron density functional theory using the В3LYP/6-311++G (d, p) method, a theoretical mechanism of the reaction of benzoylacetylene with dyselenomalonamide is proposed. It was shown that the reaction includes the following stages: nucleophilic addition of the selenoamide fragment to the electrondeficient -carbon atom of benzoylacetylene with the formation of ketovinyl selenide and further intramolecular cyclization of the mono-derivative due to nucleophilic addition of the second selenium atom of the selenol group of the reagent via the same -carbon with the formation of a heterocyclic product.
