Abstract Selective functionalization via cleavage of the C–N bond amines has proven to be challenging partly because its relatively high dissociation energy, even though are abundant and readily available. To meet this challenge, many new transformations based on pre-activation before have been developed. Among them, conversion into quaternary ammonium salts certain advantages, such as easy preparation from primary, secondary, or tertiary amines, well stable storage usage. Although transition metal catalysis frequently applied for developing oxidative addition salts, recent studies shown a dimension by using green electro- photochemical tools. In short review, advances in electro-, photo-, photoelectrochemical driven synthetic applications summarized discussed. 1 Introduction 2 Electrochemical Driven Transformations 3 Photochemical 4 Photoelectrochemical 5 Conclusion Outlook

Abstract An iron(II)‐catalyzed three‐component reaction was developed for the construction of trichloromethylated 3‐benzylquinoxalin‐2(1 H )‐ones. This conducted through trichloromethylation alkenes with quinoxalin‐2(1 )‐ones using commercially available chloroform as trichloromethyl radical source, which provided a convenient approach toward magnified image

A 1,2,3,5-tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4-CzIPN)-photocatalyzed cascade arylation/cyclization reaction of 2-isocyanobiaryls and iodonium ylides was established for the synthesis 6-arylated phenanthridines. This is first example employing as aryl radical sources in a visible-light-induced cyclization reaction.

A visible-light-induced β-acyl difunctionalization of alkenes with acyl oxime esters and various nucleophiles was developed to achieve molecular complexity from readily available raw materials via oxidative radical-polar crossover. variety nucleophiles, including NH-sulfoximines, indoles, indazole, trimethoxybenzene, were all effectively applicable the sustainable reaction system. The novel synthetic strategy features mild conditions, a broad substrate scope (39 examples), easy scale-up, excellent regioselectivity.

A visible-light induced direct C(sp3)-H functionalization of alkylarenes with trifluoromethyl ketones has been reported to access valuable benzyl-substituted alcohols in a stoichiometric manner. Readily available petroleum-derived are employed as latent benzylation reagents. With bromine radical the hydrogen atom transfer reagent, primary, secondary, and tertiary benzyl C–H bonds suitable coupling partners. Additionally, late-stage modification bioactive molecules highlights potential application this approach.
