Redox processes are at the heart of synthetic methods that rely on either electrochemistry or photoredox catalysis, but how do and catalysis compare? Both approaches provide access to high energy intermediates (e.g., radicals) enable bond formations not constrained by rules ionic 2 electron (e) mechanisms. Instead, they 1e mechanisms capable bypassing electronic steric limitations protecting group requirements, thus enabling chemists disconnect molecules in new different ways. However, while providing similar intermediates, differ several physical chemistry principles. Understanding those differences can be key designing transformations forging disconnections. This review aims highlight these similarities between comparing their underlying principles describing impact electrochemical photochemical methods.

Selective C–C bond cleavage under mild conditions can serve as a valuable tool for organic syntheses and macromolecular degradation. However, the conventional chemical methods have largely involved use of noble transition-metal catalysts well stoichiometric perhaps environmentally unfriendly oxidants, compromising overall sustainable nature transformation chemistry. In this regard, electrochemical has been identified scalable strategy that employs electricity to replace byproduct-generating reagents. To date, progress made in area mainly relied on Kolbe electrolysis related processes. Encouragingly, more examples bonds via other maneuvers recently developed.

One of the most oft-employed methods for C–C bond formation involving coupling vinyl-halides with aldehydes catalyzed by Ni and Cr (Nozaki–Hiyama–Kishi, NHK) has been rendered more practical using an electroreductive manifold. Although early studies pointed to feasibility such a process, those precedents were never applied others due cumbersome setups limited scope. Here we show that carefully optimized procedure can enable sustainable approach NHK, even in asymmetric fashion on highly complex medicinally relevant systems. The e-NHK non-canonical substrate classes, as redox-active esters, participate low loadings when conventional chemical techniques fail. A combination detailed kinetics, cyclic voltammetry, situ UV–vis spectroelectrochemistry these processes illuminates subtle features this mechanistically intricate process.
