Organic acid catalysed Minisci-type arylation of heterocycles with aryl acyl peroxides.

A metal-free method for the Minisci-type arylation of heterocycles with aryl acyl peroxides has been reported. This strategy enables the rapid and simple synthesis of a series of Minisci-type adducts from commercially available starting materials without metal catalysts. A free-radical-pathway mechanism is suggested for this transformation.
