Transition-metal-free synthesis of 5-amino-1,2,3-triazoles via nucleophilic addition/cyclization of carbodiimides with diazo compounds

A simple and transition-metal-free strategy to construct 5-amino-1,2,3-triazoles using carbodiimides and diazo compounds has been developed. This protocol involves a cascade nucleophilic addition/cyclization process and is accomplished under mild conditions. Further functionalization enriched the molecular diversity of triazoles. Control experiments and DFT calculations clarify the reaction mechanism and rationalize the kinetic and thermodynamic selectivity observed in the transformation. The late-stage derivatization and gram-scale synthesis reveal the promising utility of this methodology.

[N-N=N-N]-linked fused triazoles with pi-pi stacking and hydrogen bonds: Towards thermally stable, Insensitive, and highly energetic materials

It is the main task and challenge to reach a fine balance between high energy density and good molecular stability in energetic material research. In this study, two series of energetic compounds, 3-amino-7,7′-azo-[1,2,4] triazolo[4,3-b][1,2,4]triazole and 3,6-diamino-7,7′-azo-[1,2,4]triazolo[4,3-b][1,2,4] triazole featuring the N-4 [N-N=N-N] linkage and fused triazoles, are presented. Their structures were determined by single crystal X-ray diffraction, elemental analysis, NMR, and IR spectroscopy. Their properties were studied in terms of density, thermal stability, detonation performance, and mechanical sensitivity. The N-4 [N-N=N-N] linkages accord these compounds with high heat of formation, thus increasing the detonation performance. All fused triazoles exhibit planar structures, which result in low mechanical sensitivity. Through careful investigation of crystal data, strong pi-pi stacking and extensive hydrogen-bonding interactions were observed between molecules, which gives positive impact on mechanical sensitivity and thermal stability. The properties between different cations (or ions) were carefully studied. Quantum chemistry calculations were performed to investigate the potential relationship between structures and properties. Among them, compound 5 possesses high thermal stability (T-d: 275 degrees C), good detonation performance (D: 8677 m s(-1); P: 36.1 GPa), and excellent insensitivity (IS: 40 J; FS: 360 N), which makes it a balanced and promising energetic material.

Ionic liquid-multi-walled carbon nanotubes modified screen-printed electrodes for sensitive electrochemical sensing of uranium

Here, two screen-printed electrodes modified with multi-walled carbon nanotubes alone (electrode III) or along with a triazole-based ionic liquid (electrode VII) were developed for sensitive uranium(VI) determination. The electrodes exhibited calibration slopes of 25.10 +/- 1.35 and 29.93 +/- 0.88 mV decade(-1) over the concentration ranges of 1.0 x 10(-5)-1.0 x 10(-1) and 4.7 x 10(-7)-1.0 x 10(-1) mol L-1 for electrodes III and VII, respectively. The electrodes showed fast response times with a service life exceeding 5 months. The electrodes revealed good thermal stability and fairly high uranium(VI) selectivity over many cations and anions. The electrodes were successfully employed for sensitive detection of uranium(VI) in different water samples.

Copolymerization of o-phenylenediamine and 3-Amino-5-methylthio-1H-1,2,4-triazole for tuned optoelectronic properties and its antioxidant studies

The functionalization of conjugated polymers via copolymerization is one of the most pliable methods adopted to enhance their photophysical and optical properties. The current work accounts for the first-time copolymerization of o-phenylenediamine (OPD) with 3-Amino-5-methylthio-1H-1,2,4-triazole (AMTT) in a 1:1 molar ratio, using potassium dichromate (K2Cr2O7) as an oxidant and surfactant sodium dodecyl sulfate (SDS) as a soft template. Spectral, thermal, morphological, and optical studies through Fourier transform infrared spectroscopy, UV-Vis spectroscopy and TGA confirmed the copolymerization of poly(OPD-co-AMTT). The analysis of FTIR spectra showed the presence of benzenoid and quinonoid moiety in almost equal proportion. UV-Vis spectroscopy revealed high oscillator strength for the synthesized copolymer. The study of fluorescence spectra revealed that the quantum yield was dependent on the monomer composition in the copolymer. XRD and TEM studies revealed structural modifications in the morphology of the polymers on copolymerization while thermal studies suggested graft copolymerization. Antioxidant studies revealed significant antioxidant activity of tailored copolymer against DPPH free radical and hydrogen peroxide. (C) 2020 Elsevier B.V. All rights reserved.

Dual-supramolecular contacts induce extreme Hofmann framework distortion and multi-stepped spin-crossover

An extended nitro-functionalised 1,2,4-triazole ligand has been used to induce considerable lattice distortion in a 2-D Hofmann framework material via competing supramolecular interactions. Single crystal X-ray diffraction analyses on [Fe-3(N-cintrz)(6)(Pd(CN)(4))(3)]center dot 6H(2)O (N-cintrz: (E)-3-(2-nitrophenyl)acrylaldehyde) reveal a substantial deviation from a regular Hofmann structure, in particular as the intra- and inter-layer contacts are dominated by hydrogen-bonding interactions rather than the typical pi-stacking arrays. Also, the 2-D Hofmann layers show an assortment of ligand conformations and local Fe-II coordination environments driven by the optimisation of competing supramolecular contacts. Temperature-dependent magnetic susceptibility measurements reveal a two-step spin crossover (SCO) transition. Variable temperature structural analyses show that the two crystallographically distinct Fe-II centres, which are arranged in stripes (2 : 1 ratio) within each Hofmann layer, undergo a cooperative HS <-> HS/LS <-> LS (HS = high spin, LS = low spin) transition without periodic spin-state ordering. The mismatch between crystallographic (2 : 1) and spin-state (1 : 1) periodicity at the HS : LS step provides key insight into the competition (frustration) between elastic interactions and crystallographically driven order.
