摘要：

An efficient and green protocol for the synthesis of 2,5-disubstituted 1,3,4-oxadiazoles by one-pot reaction of different aromatic carboxylic acids and benzoyl hydrazides using natural alumina, alumina sulfuric acid (ASA), nano-gamma-alumina and nano-gamma-alumina sulfuric acid (nano-gamma-ASA) under microwave irradiation and solvent-free conditions was developed. Short reaction times, mild reaction conditions, easy work-up, and high yields are the main advantages of this methodology. The catalysts could be recovered and reused for the subsequent reactions without any appreciable loss of efficiency.
