TL;DR: In the presence of sodium nitrite, the reaction of methyl anthranilate and 2-aminopyridine or o-aminobenzoic acid gives two triazenes, 1]-(2-carboxymethyl)benzene]-3-[2-pyridine]triazene (HL) and 1-[(2carboxyethyl)-benzenes]-3]-o-amino acid]triaxene (H2L′), respectively, which have been characterized by X-ray crystallography, 31P NMR spectra,

TL;DR: In this paper, a new procedure for the synthesis of highly substituted 1,3-diaminopyrazoles is described, where 1-alkynyltriazenes and imines are used as substrates.
Abstract: A new procedure for the synthesis of highly substituted 1,3-diaminopyrazoles is described. As substrates, we have employed 1-alkynyltriazenes and imines. The formation of pyrazoles was achieved by two-fold C-N coupling reactions in the presence of (JohnPhos)AuCl and AgNTf2 as catalyst precursors. The regioselectivity of the reaction was inferred from a crystallographic analysis of one reaction product.

TL;DR: In this article, 5-Azidotriazoles bearing a thiazole, benzothiazole or pyridine ring at the 4 position were synthesized and thermolyzed at 60°C.
Abstract: 5-Azidotriazoles bearing a thiazole, benzothiazole or pyridine ring at the 4-position were synthesized and thermolyzed at 60°C. Whereas the 5-azido-4-(thiazol-2-yl)triazole 4 decomposed with extrusion of nitrogen and formation of the triazene 5 as the sole reaction product, the 5-azido-4-(benzothiazol-2-yl)triazoles 11a,b furnished mixtures of the triazenes 12a,b and the tetrazoles 14a,b. In the case of the 5-azido-4-(2-pyridyl)triazoles 17a-d, the product distribution was found to depend strongly on the N-1 aryl substituent, favouring the tetrazole 20 by increasing the electron-withdrawing capacity of this group.

TL;DR: The efficient esterification of various sulfonic acids and sulfonates using polymer-bound triazenes based on the triazene T2 linker is described and phosphoric and phosphinic acids have been converted into the corresponding esters as well.
