CuI 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.
