Abstract Azomethines is a class of compounds, which have traditionally served as electrophilic substrates, but their reactions with radicals long been limited. Photocatalysis provided ample opportunities for promoting these reactions, wide variety reagents serving precursors radicals. Besides regular addition mode at the azomethine fragment, oxidative pathway, in C=N bond remains product, has become possible by proper selection redox catalyst. This review summarizes new developments this rapidly developing field over past five years. New concepts on activation towards radical attack are discussed.

Hydrofluoroalkylation of alkenes with organozinc reagents under photocatalytic conditions is described. The fluorinated alkyl radicals were generated from organozincs by the single electron oxidation carbon-zinc bond. radical addition step followed either hydrogen atom transfer for unactivated olefins or a reduction/protonation sequence strongly accepting arylidenemalononitriles.

Abstract Mannich‐type reactions involving alkylzinc reagents have been developed using different strategies. We show that the addition of these organometallic species to sulfonyl imines occurs upon simple heating and affords Mannich products in moderate excellent yields (14 examples, 30–99 %). Interestingly, N ‐alkyl were also found be suitable partners after activation as an acyliminium by acetyl chloride (12 49–86 %) or, more originally, TMSCl 26–87 These methods proved complementary, leading preparation both ‐protected secondary or tertiary amines N‐unprotected good yields, with increased eco‐compatibility, under conditions.

A visible-light-mediated decarboxylative radical alkylation of glyoxylimines for preparing α-alkylated unnatural amino acid derivatives was developed.Various alkyl radicals generated by tetrachloro-N-hydroxyphthalimide (TCNHPI) active esters were added to imines in good yields under visible light irradiation.Iridium complex selected as photocatalyst and also, Hantzsch ester (HE) hydrogen transfer reagent essential.Fluoboric (HBF4) significantly improved the yield.Mild reaction conditions showed wide substrate scopes.In addition, straightforward efficient one-pot procotol, involved a multicomponent ethyl glyoxalate, primary amine TCNHPI occurred smoothly.This scheme provides new method synthesis derivatives.Keywords photocatalysis; N-
