CUL NANOPARTICLES AS A REUSABLE HETEROGENEOUS CATALYST FOR THE ONE-POT SYNTHESIS OF N-CYCLOHEXYL-3- ARYL-QUINOXALINE-2- AMINES UNDER MILD CONDITIONS

CuI nanoparticles as an expedient and recyclable catalyst for the synthesis of N-cyclohexyl-3-aryl-quinoxaline-2-amines in ethanol via a multi-component reaction are established. The products were separated from the catalyst simply by filtration. The catalyst could be recycled and reused for several times without noticeably decreasing the catalytic activity. 2012 JNS All rights reserved Article history: Received 11/2/2012 Accepted 18/5/2012 Published online 1/6/2012
