Fig. 1: Activation of aryl halides and aryl radical-mediated NHC catalysis.
From: Aryl radical-mediated N-heterocyclic carbene catalysis
a Oxidative addition of aryl halide to transition metal. TM, transition metal. b Organic electron donor induced aryl radical generation (recent advance). SET, single electron transfer. OED, organic electron donor. c Generation of aryl radical through NHC catalysis (working hypothesis). d Arylacylation of alkene and C(sp3)–H acylation through NHC catalysis (this work). 1,5-HAT, 1,5-hydrogen atom transfer.
