Sustainable and environmentally benign synthesis methods have captured researchers' minds in recent times and have contributed a lot towards the green synthesis of organic compounds. This work presents an efficient green method for synthesizing 2-formyl thiophene using a newly designed Pi-MnO2 deposited on poly-3-thienylacetic acid coated Toray carbon fiber paper (PThAA-Pi-MnO2-TCFP) electrode. Cyclic voltammetry (CV), chronoamperometry (CA) and bulk electrolysis (BE) techniques were employed for the optimization and synthesis of 2-formyl thiophene and the product obtained was characterized by proton nuclear magnetic resonance (1HNMR) spectroscopy. The efficacy of the developed electrode was examined by different electrochemical and physicochemical studies. It is an intriguing approach for the 4-acetamido-TEMPO (4-ACT) mediated, PThAA-Pi-MnO2-TCFP catalyzed electro-oxidation of thiophene-2-ylmethanol (TM). This method is handy and reasonably practical since the developed electrocatalyst is inexpensive, and the synthesis is environmentally benign. Hence it is a highly efficient method for synthesizing 2-formyl thiophene, a much sought-after starting material in pharmaceuticals, agrochemicals, and cosmetics. 2023
