Synthesis of Triazolium Inner Salts by Thiocyanation of Aldehyde‐Derived HydrazonesMetal-free * 1,3-Shift * Thiocyanation * Inner salt * HydrazoneSynthesis of vinyloxyimidazopyridine with complete regio and stereoselectivity has been achieved by the Cu(I)-catalyzed three-component coupling of 2-...
Scheme 9. Synthesis of copper complexes by deprotonation of triazolium salts. Jin Zhang et al. used the same base, namely KOt-Bu in the presence of CuCl to obtain the thiazolylidene–Cu(I) complex 20 (Scheme 10) [23]. Download: Download high-res image (25KB) Download: Download full-si...

In this context, we reported the synthesis and characterization of new molecules, namely 5-substituted cyclooctene monomers with an ionic triazolium salt pendant with different counteranions (iodide, hexafluorophosphate, and bis(trifluoromethylsulfonyl)imide. We have chosen, substituted cyclooctenes as ...

4-Amino-l-(cyanomethyl)-1,2,4-triazolium dinitramide was synthesized by quaternisation of 4-Amino-1,2,4-triazole with chloroacetonitrile and subsequent anion metathesis. The product was characterized by ~1H-, ~(13)C-NMR, FTIR, RAMAN, thermal analysis (DSC, TGA), density, impact and ...
Synthesis of aryl‐functionalized, 1,5‐disubstituted 1,2,3‐triazoles and derivatives by arylation of zwitterionic ruthenium triazolato complexes The synthesis of a series of ruthenium 1,5‐disubstituted 1,2,3‐triazolato complexes, 1,5‐disubstituted 1,2,3‐triazoles, and a triazolium salt is...
Directed transformation of available natural compounds with native biological activity is a promising area of research in organic and medicinal chemistry a
Salt 5 crystallizes in water with the monoclinic P21/c space group with a density of 1.77 g cm−3 (100 K) and four molecules per unit cell. The molecular unit of 5 is displayed in Fig. 4, indicating the composition of two picrate ions with the cation of compound 1. The ...
Simple azide alkyne click reaction using three fold excess of dibromoethane afforded 1-(2-bromoethyl)-4-phenyl-1H-1,2,3-triazole. The latter on dehydrobromination yields N-vinyl triazole (N tzl ) which is subsequently used for preparing its triazolium salt. Further, N tzl –Pd–N tzl ...
