Various sulfonamides have been synthesized from triazenes and sulfur dioxide. In the presence of just a catalytic amount of BF3· OEt2, a series of 1-aryl-triazenes were converted into sulfonyl hydrazines in good to excellent yields. When using CuCl2 as the catalyst, the corresponding sulfonamides can be produced from the 1-aryl triazenes in good yields. This journal is the Partner Organisations 2014.
Synthesis of 1-aryl-3,3-disubstituted triazenes on ion-exchange resin support

Diazonium ions have been immobilized on a cation exchanger followed by N-coupling on a 2-amine to give the 3,3-disubstituted-1-aryltriazenes as the only product. Reaction is clean and work up procedure simple.
