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
Transition metal free oxygenation of 8-aminoquinoline amides in water

The oxygenation of 8-aminoquinoline amides by benzoyl peroxide at the C5 position in water is developed in the absence of a transition metal catalyst, affording the desired products in moderate to good yields of up to 88%. Mechanism studies reveal that the reaction would involve a radical process.
A highly efficient Pd-catalyzed decarboxylative ortho-arylation of amides with aryl acylperoxides

supporting information, p. 14862 - 14865 (2014/12/11)
An efficient Pd-catalyzed decarboxylative ortho-arylation of amides with aryl acylperoxides was developed. A variety of anilides reacted with aryl acylperoxides to afford the corresponding ortho-arylation products, and N-methoxyarylamides generated phenanthridinones. This journal is
Palladium(II)-catalyzed othro-C-H-benzoxylation of 2-arylpyridines by oxidative coupling with aryl acylperoxides

, p. 4403 - 4418 (2013/05/22)
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.
Preparation of new substituted bis(benzoyl) peroxides under aqueous conditions in the presence of stearyltrimethylammonium chloride

, p. 397 - 405 (2007/10/03)
A series of new substituted bis(benzoyl) peroxides has been synthesised from their corresponding acid chlorides in high yield. The reactions were carried out in aqueous sodium peroxide solution and butanone in the presence of 0.5% stearyltrimethylammonium chloride (STAC) at a temperature below 15°C. STAC improved the purity, and the fast addition improved the yield of the peroxides. Mass spectral analysis of substituted bis(benzoyl) peroxides using EI has been carried out for accurate mass determinations. Springer-Verlag 2003.
Preparation of liquid substituted benzoyl peroxide mixtures
Moorhoff, Cornelis M.,Braybrook, Carl
, p. 339 - 361 (2007/10/03)
A series of alkyl substituted benzoyl peroxide mixtures were synthesised from two or three acid chloride combination in aqueous sodium peroxide and butanone solutions in the presence of 0.5 percent stearyltrimethylammonium chloride. Some of these benzoyl peroxide mixtures were found to be liquids at -10 deg C.
