Annulation‐Induced Hidden Reactivity of the 1,2,4‐Triazole Backbone

Angewandte Chemie International Edition, 2023
AbstractTriazoles are an important class of compounds with widespread applications. Functionalization of the triazole backbone is thus of significant interest. In comparison to 1,2,3‐triazoles, C−H activation‐functionalization of the congeners 1,2,4‐triazoles is surprisingly underdeveloped.

Lattice vibrations of 1,2,4-triazole

Journal of the Chemical Society, Faraday Transactions 2, 1977
The far-infrared spectra of polycrystalline 1,2,4-triazole (C2N3H3) and 1-2-4-[2H3]triazole have been recorded between 250 and 20 cm–1. Raman spectra have also been measured. The assignments of the observed frequencies to translatory and rotatory lattice modes were made on the basis of isotopic shift factors.

ChemInform Abstract: MOLECULAR STRUCTURE OF 1,2,4‐TRIAZOLE

Chemischer Informationsdienst, 1977
Abstract The molecular structure of 1,2,4-triazole has been determined by gas phase electron diffraction. The intemuclear distances and bond angles were obtained by applying a least-squares analysis to the experimental intensity. The bond distances ( r g ) and bond angles were N 1 -N 2 = 1.380 ± 0.010 A, N 2 C 3 = 1.329 ± 0.009 A, C 3 -N 4 = 1 ...

Syntheses, Crystal Structures, Luminescent Properties, and Electrochemical Synthesis of Group 12 Element Coordination Polymers with 4-Substituted 1,2,4-Triazole Ligands

Crystal Growth & Design, 2019
The self-assembly of Zn(II), Cd(II), or Hg(II) salts with long flexible 1,2,4-triazole-based ligands resulted in coordination polymers and mononuclear complexes of diverse topology. Indeed, the 1D chain [ZnCl2(btpm)] (1) (P1), the 2D square grid [Zn(btpm)
