摘要

The advancement of these chemical transformations necessitates the optimization of conventional reaction conditions and the enhancement of catalytic system efficiency through the utilization of readily available, cost-effective raw materials that exhibit recyclability and multifunctionality, serving simultaneously as solvent, catalyst, and catalytic agent, in accordance with green chemistry principles. In this context, the present study reports the design and synthesis of [DHPZ][CuCl3]2 and [DHPZ][FeCl4]2 catalysts based on deep eutectic solvents incorporating inexpensive and abundant metals, namely copper and iron. Comprehensive characterization of these catalysts was performed using FT-IR, TGA, 1HNMR, 13CNMR, and cyclic voltammetry (CV) analyses. The catalytic performance was subsequently assessed in the electrocarboxylation reaction for the synthesis of 4-Phenyl-1,3-dioxolan-2-one derivatives 4(a-j) under optimized conditions, including ambient temperature, atmospheric pressure, an applied current of 10 mA, and a reaction duration of 1.5 h. This methodology afforded the target compounds in good to excellent yields, ranging from 89% to 97%. The synthesized derivatives were further confirmed by 1HNMR spectroscopy, CHN elemental analysis, and melting point determination.
