A pyridine-catalysed desulfonylative addition of β-diketones to arylazosulfones was developed to obtain diazenyl β-dicarbonyl compounds. The aryldiazenyl group was observed in the desired product from arylazosulfones, and this diazenylation reaction was achieved via a possible rearrangement process based on diaziridine ring cleavage. The scope of the protocol was investigated and a plausible mechanism was given. (Figure presented.).
