IR-Spectroscopic Study of Adsorption of Aminoazoles on Oxide Catalysts of Biginelli Reaction

Аннотация

Adsorption of 5-aminotetrazole and 3-aminotriazole on the surface of nanosized oxides of Al and Si–Ti, which are catalysts of the Biginelli reaction with the participation of aminoazoles, have been studied using the method of IR spectroscopy. It has been shown that 5-aminotetrazole and 3-aminotriazole interact with the Brønsted base centers on the oxide surface, with the behavior of aminoazole in the Biginelli reaction being determined by the coordination.
