A mild and convenient protocol for the oxidative cleavage of 1,3-diketone compounds is described. Under metal-free conditions, the method converts the 1,3-dicarbonyls into amides when treated with (nBu4N)N3 and iodine in the presence of an amine at room temperature. Using this method, a range of 1,3-dicarbonyls with various structural motifs including sterically demanding substituents and ordinary functional groups were easily fragmented, and it is demonstrated that cyclic 1,3-dicarbonyls can be directly transformed into acyclic diamides through ring-opening. Initial mechanistic studies show that diazidation of the enol form is followed by nucleophilic substitution with the amine.

The reaction of 3,4-bis(p-bromomethylphenyl)-1,2,5-thiadiazole (1) with bis(N-alkylaminomethyl)benzenes under high dilution conditions gave the diaza1,2,5-thiadiazolo[3.3.2]cyclophanes, while 1 reacted with xylylenediamines to give cupped diazathiadiazolo
