, p. 1373 - 1376 (2016)
By using a new porphyrin-based linker, two unusual mixed-valent Ag(i,ii)- and Cu(i,ii)-organic networks were synthesized. Most strikingly, 1 and 2 exhibit highly efficient catalytic activities for the azide-alkyne "click" reaction and oxidation of ethylbe

A novel procedure for catalyst recycling is described. Copper(I)-based catalysts, equipped with an affinity tag, are isolated from crude reaction mixtures on the basis of quadruple hydrogen-bonding interactions using a resin functionalized with complement

We report a bottom-up approach to immobilize catalysts into MOFs, including copper halides and gold chloride in a predictable manner. Interestingly, the structures of MOFs bearing NHC metal complexes maintained a similar 4-fold interpenetrated cube. They

In this study, we report a highly stable and efficient single-atom Cu dispersed on N-doped porous carbon as a superior catalyst for azide-alkyne cycloaddition reaction. A broad set of 1,4-disubstituted 1,2,3-triazoles was synthesized in high to excellent
Resorcin[4]arene-based Cu(I) binuclear and mononuclear complexes as efficient catalysts for azide-alkyne cycloaddition reactions

In this study, three fascinating resorcin[4]arene-based Cu(I) complexes, named [CuCl (TPC4R)] (1), [CuBr (TPC4R)] (2), and [Cu2I2(TPC4R)] (3) were prepared by using a pyrimidine-functionalized resorcin[4]arene ligand (TPC4R). In 1 an

Three distinctive coordination polymers [Cu2L2]·0.5CH3OH·1.5H2O·2CN (1), [CdCl2L]·5DMF·2CH3OH·2H2O (2) and [Cd2L(bdc)2(DMF)]·2DMF·3CH3OH·H2
Dipolar HCP materials as alternatives to DMF solvent for azide-based synthesis
Bai, Rongxian,Gao, Feng,Gu, Yanlong,Li, Minghao
, p. 7499 - 7505 (2021/10/12)
Hypercrosslinked polymers HCP-DMF and HCP-DMF-SO3H containing abundant and flexible DMF moieties were designed and synthesized. Benefitting from the solvation microenvironment provided by the pseudo-DMF moities, the polar HCPs manifested outstanding performances in the conversions of NaN3 to benzylic azides and 1,2,3-triazoles in EtOH (95%), respectively, avoiding the use of risky DMF and improving the separation processes of the products.
A novel route to 1,4-disubstituted-1,2,3-triazoles through metal-free decarboxylative azide-alkene cycloaddition

A collection of 1,4-disubstituted 1,2,3-triazoles was achieved by decarboxylative [3 + 2] cycloaddition of organic azides and cinnamic acids. Metal-free condition, high regioselectivity and easy accessibility of starting materials are the salient attributes of this protocol.
Melamine-supported nickel oxide nanoparticles as a good alternative to conventional copper catalysts for the regioselective synthesis of triazole derivatives in water

Photosensitizing assemblies of pyrazine derivative PDA have been developed which exhibit a high photostability, ‘lighted’ excited state, balanced redox potential, high transportation potential and activate oxygen via type-I pathway only. These PDA assemblies in combination with Cu(II) ions catalyze the CuAAC reaction via in situ reduction of Cu(II) ions without any reducing or stabilizing agent. The present protocol has wide substrate scope with recyclability of the catalytic system up to six catalytic cycles and is applicable to gram-scale synthesis.
