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.

We developed a palladium-catalyzed carbonylative Sonogashira reaction with aryl triazenes and alkynes as substrates and methanesulfonic acid as the additive. A series of α,β-ynones were synthesized by this alternative procedure. Notably, bromides, iodides

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.
