Access to (Z)-β-Substituted Enamides from N1-H-1,2,3-Triazoles

A direct ring-opening/nucleophilic substitution reaction of N1-H-1,2,3-triazoles has been described. Divergent (Z)-β-halogen- or sulfonyl-substituted enamides could be stereospecifically synthesized in a tunable manner. This strategy might not only enable

Direct Synthesis of 4-Aryl-1,2,3-triazoles via I2-Promoted Cyclization under Metal- And Azide-Free Conditions

We herein report an iodine-mediated formal [2 + 2 + 1] cyclization of methyl ketones, p-toluenesulfonyl hydrazines, and 1-aminopyridinium iodide for preparation of 4-aryl-NH-1,2,3-triazoles under metal- and azide-free conditions. Notably, this is achieved

Magnetically separable ZnFe2O4 nanoparticles: A low cost and sustainable catalyst for propargyl amine and NH-triazole synthesis

The multicomponent reaction (MCR) strategy for the construction of important molecular scaffolds is in trending nowadays and among them, A3-coupling stands in a significant position. Aldehyde, amine and alkynes are coupled in this particular reaction via C-H activation process. Herein, we have reported zinc ferrite nanoparticles as magnetically separable heterogeneous catalyst for A3-coupling reaction with attractive attributes like excellent productivity, selectivity and better reusability. Moreover, the catalyst can also be effectively applied for the synthesis of various NH-triazoles with quantitative yields of the products. A plausible mechanism has been proposed for the synthesis of NH-triazoles followed by validation with computational study.

Silica immobilized copper N-heterocyclic carbene: An effective route to 1,2,3-triazoles via azide-alkyne cycloaddition and multicomponent click reaction

A new silica supported copper N-heterocyclic carbene (Cu-NHC@SiO2) complex is prepared and characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS) analyses. This complex is an efficient and easily retrievable catalyst for 1,2,3-triazole synthesis through direct azide-alkyne cycloaddition reaction as well as one-pot reaction using arylboronic acids. This catalytic system is also suitable for synthesis of 4-aryl-NH-1,2,3-triazoles from diverse benzaldehydes. Further, the catalyst can efficiently be recycled up to fifth cycle for all the three methods of 1,2,3-triazole synthesis through direct azide-alkyne cycloaddition and multi-component reactions.

A green metal-free "one-pot" microwave assisted synthesis of 1,4-dihydrochromene triazoles

The synthesis of several 4-aryl-1,4-dihydrochromene-triazoles was achieved via a metal-free "one-pot"procedure using PEG400 as the sole solvent in an eco-friendly process. Using microwave irradiation, the triazole derivatives were obtained in good yields and short reaction times starting from readily accessible building blocks.

A mineralogically-inspired silver-bismuth hybrid material: An efficient heterogeneous catalyst for the direct synthesis of nitriles from terminal alkynes

The synthesis and characterization of a silver-containing hybrid material is reported as a novel heterogeneous noble metal catalyst. In order to eliminate the need for traditional immobilization techniques, and to create a solid material with structurally-bound silver catalytic centers, the layered structure of a naturally occurring mineral served as the basis of the initial catalyst design. The novel material was prepared by means of the urea-mediated homogeneous precipitation of the corresponding metal nitrates, and was fully characterized by means of diverse instrumental techniques (X-ray diffractometry, Raman, IR, UV-Vis, EPR, X-ray photoelectron spectroscopies, thermal methods as well as atomic force, scanning and transmission electron microscopies). The as-prepared material exhibited outstanding activity in silver-catalyzed CC bond activation to yield organic nitriles directly from terminal alkynes with less environmental concerns as compared to the classical synthesis methods. The effects of the reaction time, the temperature, as well as the role of various solvents, nitrogen sources and additives were carefully scrutinized in order to achieve high-yielding and selective nitrile formation. The heterogeneous nature of the reaction was verified and the solid catalyst was recycled and reused numerous times without loss of its activity or degradation of its structure, thereby offering a sustainable synthetic methodology.
