A new and efficient method for diazenylation reactions was developed with a Sc­(OTf)3-catalyzed nitrogen–nitrogen bond cleavage process with triazenes. The transfer diazenylation reactions accommodate a diverse range of active methylene substrates including simple ketones to give aliphatic azo compounds that are of significant potential as azo prodrugs in high yields under mild conditions.
