Abstract
1,4-Diazabicyclo[2.2.2]octane has been explored as an efficient catalyst to effect the between malononitrile, 4-arylurazoles, and aromatic aldehydes in ethanol under ultrasound irradiation conditions. The reactions proceeded very rapidly under mild conditions to furnish the corresponding pyrazolo[1,2- a][1,2,4]triazole-1,3-dione derivatives in excellent yields. [ABSTRACT FROM AUTHOR]
