Electrochemical Hydrogenation of N‐Heterocycles and Related Substrates: A Mini‐Review

Electrochemical Science Advances, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 17, 2024

ABSTRACT Catalytic hydrogenation refers to the (often) metal‐mediated addition of dihydrogen (H 2 ) equivalents unsaturated compounds form new element‐hydrogen bonds. This conceptually simple reaction is ubiquitous in production a vast number essential chemicals. Despite growing recognition importance sustainability manufacturing, use fossil‐derived hydrogen gas and precious metal catalysts remains widespread. Electrochemical variants these processes are an appealing alternative, especially those that can make sustainable Brønsted acids, more abundant electrode materials renewable electricity. In this mini‐review, we give selective overview electrochemical methodologies for N‐ heterocycles some related substrates from specific perspective synthetic chemistry made possible by increasingly popular approach.

Carbohydrate fuel cells garner much research interest as the world's focus shifts from fossil fuels to renewable energy. Many catalyst options are available for carbohydrate cell development, including enzymes and microbes, various metal-based catalysts, natural or synthetic mediators. Research challenges include low power output, system fouling poisoning, inefficient electron release, complex mechanisms, with multiple pathways leading product selectivity. Here, we further investigate a novel approach catalyze oxidation using Au electrodes viologen self-assembled monolayers (SAMs). SAM-mediated have potential address of other systems by protecting electrode surface controlling local concentration structure increase current generation. The effects increasing pH on dihydroxyacetone (DHA) three SAMs presented. Current generated during DHA at varying were measured compared those bare performance. Two produced more than elevated pH. SAM peak per molecule both dilute concentrated homogeneous in same setup. These results demonstrate benefits limitations modified redox-active groups production electricity simple sugars sources. encouraging development new strategies electrical generation resources.
