A directarylation of unactivated benzene with acyl peroxides was developed, affording biaryls in good to excellent yields. The transformation underwent radical pathway under metal-free, base-free and additive-free conditions with good functional groups compatibility.

This communication reports an efficient microwave-promoted radical addition/cyclization reaction of biaryl vinyl ketones with diacyl peroxides in water undermetal-freeconditions. A series of 10-methyl-10-benzyl(alkyl)phenanthren-9(10H)-ones were obtained in high yields with good functional group tolerance.
