We have developed a method for the direct sulfonamidation of 2-aryl-1,2,3-triazole N-oxides using sulfonyl azides as the amino source to release molecular nitrogen as the sole by-product. This protocol exhibits excellent functional group tolerance and proceeds efficiently under external oxidant-free conditions. Various 2-(2-sulfonamidoaryl)-1,2,3-triazoles were prepared in up to 97% yields for 25 examples with excellent regioselectivity.

Oxygenation of 4-nitrophenylhydrazones of α,β-enones with Co(Salpr), a five coordinated cobalt(II) Schiff base complex, results in the oxidative cleavage of the double bond in the substrate.A proposed mechanism involves the decomposition of peroxidic inte
