Photoresponsive triazole-based donor-acceptor molecules: Color change and heat/air-stable diradicals

Photoinduced generation of stable radicals is important for photochromism, photoswitching and other applications, but was limited only to a few systems. An unprecedented series of triazole-based donor-acceptor organic molecules were found to form heat/air

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.

Method for preparing 1,2,3-triazole compound by heterogeneous copper catalysis in one pot

The invention relates to a method for preparing a 1-aryl-4-substituted-1,2,3-triazole compound shown as a formula (II). The method comprises the following steps: mixing arylboronic acid (1), NaN3, a heterogeneous copper catalyst and solvent water, performing a stirring reaction at 25-60 DEG C for 4-8 hours, performing TLC (thin-layer chromatography) monitoring till the arylboronic acid (1) is completely converted, replacing air in the reaction system by using N2, adding a terminal alkyne (2), performing a reaction at 40-80 DEG C for 6-10 hours under the protection of N2, and performing post-treatment on the reaction solution to obtain a product (II). By adopting the preparation method, Cu-coated SBA-15-PTAA is used as a catalyst, a series of 1-aryl-4-substituted-1,2,3-triazole compounds are prepared through a one-pot Chan-Lam/Click series method without additionally adding a reducing agent, the developed catalytic method is green, safe and economical, the amount of three wastes (wastegas, waste water and industrial residue) is small, the yield of a target product is high, and the substrate application range is wide.

Ag2CO3-catalyzed cycloaddition of organic azides onto terminal alkynes: A green and sustainable protocol accelerated by aqueous micelles of CPyCl

Using catalytic amount of Ag2CO3 a simple, efficient and copper free green protocol has been developed to synthesize 1,4-disubstituted 1,2,3-triazoles regioselectively. Here, the cationic surfactant, cetylpyridinium chloride (CPyCl) in water provides a micellar media and accelerates the subsequent Ag(I)-catalysed azide-alkyne cycloaddition (AgAAC) reaction by increasing the concentration of reactants in the micellar pseudophase. Our method is found to be environmentally friendly from E-factor measurement. The surfactant, CPyCl is found to be nontoxic.

Dual roles of substituted thiourea as reductant and ligand in CuAAC reaction

A highly efficient catalytic system, CuSO4·5H2O/1-(4-methoxyphenyl)-3-phenylthiourea, for the copper(I)-catalyzed azide–alkyne cycloaddition reaction (CuAAC) was discovered. In the above catalytic system, substituted thiourea acts both as a reductant and a ligand. CuSO4·5H2O/1-(4-methoxyphenyl)-3-phenylthiourea is both an economical and efficient catalyst for the CuAAC reaction. In addition, the new catalytic system has advantageous features including mild and green reaction conditions, and broad substrate compatibility. A variety of 1,4-disubstituted 1,2,3-triazoles have been prepared with good to excellent yields with the CuSO4·5H2O/1-(4-methoxyphenyl)-3-phenylthiourea catalytic system in aqueous solution.
