σ-Bond nucleophiles and molecular oxygen transform aryl diazonium salts into aryl radicals. Experimental and computational studies show that Hantzsch esters transfer hydride to aryl diazonium species, and that oxygen initiates radical fragmentation of the diazene intermediate to produce aryl radicals. The operational simplicity of this addition-fragmentation process for the generation of aryl radicals, by a polar-radical crossover mechanism, has been illustrated in a variety of bond-forming reactions.

The cathodic reduction-induced cross-coupling of arenediazonium salts and heteroarenes was employed to prepare heterobiaryl derivatives. This reaction is attractive because it allows the direct arylation of an aromatic C-H bond in a heteroarene derivative. A radical chain mechanism appears to be involved.
Original design of fluorescent ligands by fusing BODIPY and melatonin neurohormone

supporting information, p. 158 - 161 (2014/03/21)
An original design and synthesis of fluorescent ligands for melatonin receptor studies is presented and consists in the fusion of the endogenous ligand with the fluorescent BODIPY core. Probes I-IV show high affinities for MT1 and MT2 melatonin receptors and exhibit fluorescence properties compatible with cell observation.
