Fabrication of an economical and environmentally friendly electrode utilizing fullerene modified with L-proline and coated with copper nanoparticles for enantioselective electro-organic henry reaction in the presence of NaCl electrolyte

This study focuses on the fabrication of an economical and environmentally friendly electrode for chiral electro-organic synthesis of (S)-2-Nitro-1-Phenylethanol derivatives 4(a-m) in good to excellent yields (90–96 %). The electrode is constructed using Fullerene modified with l-Proline and coated with copper nanoparticles (ox-Fullerene-Pro@Cu). The designed electrode aims to facilitate the synthesis of (S)-2-Nitro-1-Phenylethanol 4(a-m) derivatives efficiently. The utilization of sodium chloride as an electrolyte further enhances the electrochemical reaction. Following the electrode synthesis, comprehensive characterization and identification were conducted utilizing SEM, EDS, TEM, XPS, XRD, TGA, BET, CV and FT-IR analyses. The electrode's cost-effectiveness and eco-friendly nature make it a promising candidate for sustainable electro-organic synthesis processes. The synthesized (S)-2-Nitro-1-Phenylethanol derivatives 4(a-m) derivatives were identified and their properties reported through melting point, 1HNMR, Mass and CHN analyses.
