, p. 1086 - 1089 (2014)
A practical and efficient methodology for the formation of C-O bonds on the porphyrin/chlorin periphery was developed. The aroyloxy-substituted porphyrins and chlorins related to chlorophyll-a at the β- and meso-positions, respectively, were conveniently synthesized by the free radical substitution reaction with benzoyl peroxide and its homologs.
Aryl acyl peroxides for visible-light induced decarboxylative arylation of quinoxalin-2(1: H)-ones under additive-, metal catalyst-, and external photosensitizer-free and ambient conditions

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
An unprecedented cobalt-catalyzed selective aroylation of primary amines with aroyl peroxides

A novel and facile cobalt-catalyzed selective aroylation of primary amines with aroyl peroxides was developed for the synthesis of aryl amides. It was unprecedented that C[sbnd]N bond formation product was selectively generated without the common N[sbnd]O bond formation product. Aroyl peroxides act as the sole aroylation reagent without additional base or oxidant. The reactions proceeded under mild conditions and showed broad substrates scope with a series of primary amines and aroyl peroxides.
Uncatalyzed, on water oxygenative cleavage of inert C-N bond with concomitant 8,7-amino shift in 8-aminoquinoline derivatives

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.
Thermoinduced Free-Radical C-H Acyloxylation of Tertiary Enaminones: Catalyst-Free Synthesis of Acyloxyl Chromones and Enaminones

In this paper, the direct acyloxylation of the α-C(sp2)-H bond in tertiary β-enaminones is accomplished under catalyst-free conditions and ambient temperature by using aroyl peroxides as coupling partners. By means of a thermoinduced free-radical pathway, the present method enables facile and efficient synthesis of both acyloxylated chromones and enaminones.

The aroyloxy-substituted porphyrins and chlorins related to chlorophyll-a at the β- and meso-positions, respectively, were conveniently synthesized by the free radical substitution reaction with benzoyl peroxide and its homologs.
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.
