Copper nanoparticles in an ionic liquid: an efficient catalyst for the synthesis of bis-(4-hydroxy-2-oxothiazolyl)methanes
摘要:
Copper nanoparticles were synthesized and characterized by TEM, XRD and UV-vis techniques. The copper nanoparticles in an ionic liquid were employed as a recyclable catalyst for the synthesis of bis-(4-hydroxy-2-oxothiazolyl)methanes in excellent yields and in short reaction times.

Abstract A green and convenient approach for the synthesis of a series of 5,5'-(arylmethylene)bis(4-hydroxythiazole-2(3H)-one) by the reaction of aryl aldehydes, monochloroacetic acid and ammonium thiocyanate in water/trifluoroethanol(TFE) (1:1) under ultrasound irradiation at room temperature is described. This method provides several advantages such as environmental friendliness, shorter time, excellent
