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 and hydroxyl groups could be well-tolerated under these reaction conditions.

Phenols have been synthesized in excellent yields using a cationexchangeresin (H+ form) assisteddecomposition of 1-aryl-3,3-dialkyltriazanes in the presence of water. This method is also amenable to a high yield and high enrichment synthesis of oxygen-17 and 18 labeled phenols.
