Aryl radicals were generated for the first time from cheap and easily available aryl acyl peroxides in eco-friendly ethyl acetate under ambient conditions and visible-light illumination in the absence of any additive, metal catalyst, or external photosensitizer. The present arylation of quinoxalin-2(1H)-ones was chemo- and regioselective, and provided good access to various 3-arylquinoxalin-2(1H)-ones. This journal is

Oxygenative cleavage of an inert CAr-NH2 bond with concomitant 1,2 amine migration in 8-aminoquinoline derivatives is reported in water at room temperature. The reaction is highly atom- and step-economical as both C- and N-containing fragments of the C-N bond cleavage are incorporated into the target molecule and is effected without the need for N-oxide. The reaction is scalable to gram level, and the products are useful as electrophilic partners for coupling reactions, ligands in catalysis and bioactive compounds.

Iron catalyzed site selective and chelation assisted C-H functionalization in 8-amidoquinolines is achieved. The remote C5-benzoxylation with benzoyl peroxide produced a variety of potentially bioactive 8-arylcarboxamido-5-benzoyloxy quinoline derivatives. The efficiency of the reaction reflects from the wide substrate scope with electronic differentiation on carboxamide and acyl peroxide in addition to tolerance of halo-substitutions on either of the aryls. The reaction is additive, silver free and proceeds without the exclusion of air or moisture.

A palladium(II)-catalyzed ortho-benzoxylation of 2-arylpyridines with aryl acylperoxides was developed. With pyridyl as directing group, the benzoxylation reaction exhibits remarkable regioselectivity and excellent functional group tolerance, providing the products in up to 87% yield.
Palladium-catalyzed decarboxylative arylation of C-H bonds by aryl acylperoxides
Yu, Wing-Yiu,Sit, Wing Nga,Zhou, Zhongyuan,Chan, Albert S.-C.
supporting information; experimental part, p. 3174 - 3177 (2009/11/30)
A Pd(OAc)2-catalyzed protocol for decarboxylative arylation of aromatic C-H bond was developed using aryl acylperoxides as inexpensive aryl sources. Substrates containing pyridyl, oxime, and oxazoline groups undergo effectively ortho-selective C-H arylation with excellent functional group tolerance. This arylation should begin by directing-group-assisted cyclopalladation, followed by the reaction of the palladacycle with aryl radicals generated in situ by thermal decomposition of the peroxides.
