A novel procedure for the replacement of N2 with CO of aryltriazenes has been developed. Aryltriazenes were converted to the corresponding arylamides catalyzed by 1 mol % of PdCl2/P(o-Tol)3 under CO pressure. In this process, aryldiazonium salts were generated in the presence of 40 mol % of MeSO3H. Nitrogen was released from the substrates and CO formally inserted. Aryl bromides, iodides, alkynes, and free hydroxyl groups can be tolerated in this transformation.
Catalytic conversion of aryl triazenes into aryl sulfonamides using sulfur dioxide as the sulfonyl source

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.

, p. 1178 - 1185 (2007/10/02)
1-Aryl-3,3-dialkyltriazenes have been synthesized by coupling the corresponding diazonium salts of substituted aniline derivatives with dialkylamines.The thermostability of these compounds was investigated by differential scanning calorimetry; activation
