Abstract

Abstract:

Compared with the conventional stirring method a study of catalysts and microwave power for the synthesis of Schiff bases under microwave irradiation was performed. In addition, three kinds of catalysts —— NaHSO4, AlCl3 and SbCl3 —— were employed in order to compare their catalytic activities for the synthesis of Schiff Bases. The products were characterized by IR, 1H NMR, and elemental analysis. This demonstrated that the procedure involved a short reaction time and moderate reaction conditions. Microwave power of 800?W was optimum for the reaction, and SbCl3 exhibited higher catalytic activity than the others. 6 mol％ of catalyst was sufficient to accelerate the reaction.

Key words: microwave irradiation; Lewis acid catalyst; SbCl3; Schiff bases
