The present study reports a simple protocol involving Cu/Cu₂O nanoparticles synthesis via electrochemical deposition process in 1-methylpiperidinium trifluoromethane sulphonate [HmPip][OTf] protic ionic liquid. The phase and morphology of the prepared nanoparticles were examined using different characterization techniques such as XRD, XPS, FEG-SEM, TEM, EDX, and FT-IR. A highly efficient, ligand-free method was developed to synthesize quinazolinones from substituted 2-halobenzoic acids with amidines via microwave-assisted Cu/Cu₂O nano-catalyst in ethylene glycol as a green solvent. Up to five cycles Cu/Cu₂O nanoparticles show good recyclability without loss in its activity.

质子离子液体中水辅助电化学制备Cu / Cu 2 O纳米粒子及其在喹唑啉酮合成中的催化活性

本研究报告了一种简单的协议，该协议涉及在1-甲基哌啶三氟甲烷磺酸盐[HmPip] [OTf]质子离子液体中通过电化学沉积过程合成Cu / Cu ₂ O纳米粒子。使用不同的表征技术（例如XRD，XPS，FEG-SEM，TEM，EDX和FT-IR）检查了制备的纳米颗粒的相和形态。开发了一种高效，无配体的方法，通过微波辅助的Cu / Cu ₂ O纳米催化剂在乙二醇中作为绿色溶剂，由取代的2-卤代苯甲酸与am合成喹唑啉酮类化合物。多达五个周期的Cu / Cu ₂ O纳米粒子显示出良好的可回收性，而不会损失其活性。
