Ruthenium-catalyzed cycloaddition of alkynes and organic azides
TL;DR: In this article, a convenient process for the regioselective synthesis of 1,5-disubstituted 1,2,3-triazoles and 1,4,5-trisubstitized 1, 2,3, 4,5, 5 triazoles from organic azides and alkynes employs catalytic ruthenium.

Beyond click chemistry - supramolecular interactions of 1,2,3-triazoles.
TL;DR: The intention of this review is to provide a detailed analysis of the various supramolecular interactions of triazoles in comparison to established functional units, which may serve as guidelines for further applications.

Efficient synthesis and in vitro antitubercular activity of 1,2,3-triazoles as inhibitors of Mycobacterium tuberculosis.
Poovan Shanmugavelan,Sangaraiah Nagarajan,Murugan Sathishkumar,Alagusundaram Ponnuswamy,Perumal Yogeeswari,Dharmarajan Sriram +5 more
TL;DR: In vitro antitubercular activity of these triazoles was screened against Mycobacterium tuberculosis H(37)Rv strain and four of the compounds showed MIC in the range of 1.56-3.13 μg/mL proving their potential activity.

A New Family of Ruthenium (II) Polypyridine Complexes Bearing 5-Aryltetrazolate Ligands as Systems for Electrochemiluminescent Devices
Stefano Stagni,Antonio Palazzi,Stefano Zacchini,Barbara Ballarin,Carlo Bruno,Massimo Marcaccio,Francesco Paolucci,Magda Monari,Maurizio Carano,Allen J. Bard +9 more
TL;DR: The electrogenerated chemiluminescence (ECL) of the dinuclear species has been explored, and for one of these, an exceptionally high ECL efficiency has been observed, comparable to that of [Ru(bpy)(3)](2+), which is considered a standard in ECL studies.

An empirical correction for absorption anisotropy
TL;DR: A least-squares procedure is described for modeling an empirical transmission surface as sampled by multiple symmetry-equivalent and/or azimuth rotation-equ equivalent intensity measurements.

1,3-Dipolar Cycloadditions. Past and Future†
TL;DR: In contrast to the very large number of special methods applicable to syntheses in the heterocyclic series, relatively few general methods are available as discussed by the authors, and the 1,3-dipolar addition offers a remarkably wide range of utility in the synthesis of five-membered heterocycles.
Journal ArticleDOI
Kinetics and Mechanism of 1,3-Dipolar Cycloadditions
TL;DR: Criteria for the mechanism of 1,3-dipolar cycloadditions which lead to 5-membered rings are provided by the stereoselectivity observed with cis-trans isomeric dipolarophiles, by the effect of solvent and substituents on the rate constants, and by orientation phenomena.

TL;DR: The addition of sodium azide to nitriles to give 1H-tetrazoles is shown to proceed readily in water with zinc salts as catalysts.
