1-(4-Ethynylphenyl)-3,3-dialkyltriaz-1-enes, well-known building blocks for branched dendrimer syntheses, were utilized as a new type of electron-donor component in formal [2 + 2] cycloadditions. The click-type, atom-economic reactions proceed efficiently

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
Catalytic conversion of aryl triazenes into aryl sulfonamides using sulfur dioxide as the sulfonyl source

supporting information, p. 9513 - 9516 (2014/08/18)
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.

In certain embodiments, the sulfonium compound is a triaryl sulfonium salt. Another aspect of the present invention relates to a method of obtaining a positron emission image of a mammal, comprising the steps of administering to a mammal a compound of the invention, and acquiring a positron emission spectrum of the mammal.
Synthesis of Biaryls from Aryltriazenes
Patrick, Timothy B.,Willaredt, Richard P.,DeGonia, David J.
, p. 2232 - 2235 (2007/10/02)
Aryltriazenes react with aromatic solvents in the presence of trifluoroacetic acid to produce biaryls.The mechanism of the reaction involves the formation of arenediazonium trifluoroacetates which lose nitrogen to give mainly aryl radicals.
