Cu nanoparticles immobilized on modified magnetic zeolite for the synthesis of 1,2,3‐triazoles under ultrasonic conditions
analysis, inductively coupled
plasma, X‐ray diffraction, scanning electron microscopy and transmission electron
microscopy techniques. The 1,2,3‐triazoles were readily synthesized
through using the catalyst in high yields and short reaction times...
Synthesis, characterization, and investigation of catalytic activity of copper(II) porphyrin graphene oxide for azide–alkyne cycloaddition
), thermogravimetric analysis (TGA), and inductively coupled plasma (ICP) spectroscopy. All analyses confirmed successful covalent immobilization of CuPPh on GO. The activity of the catalyst was then studied for synthesis of 1,4-disubstituted 1,2,3-triazoles...
CuII immobilized on guanidinated epibromohydrin functionalized g-Fe2O3@TiO2 (g-Fe2O3@TiO2-EGCuII): a novel magnetically recyclable heterogeneous nanocatalyst for the green one-pot synthesis of 1,4-disubstituted 1,2,3-triazoles through alkyne–azide cycload
/DTA, HRTEM, XRD, EDX, VSM, ICP and elemental analysis. The catalyst
demonstrated a superior catalytic activity towards the green one-pot synthesis of 1,4-disubstituted 1,2,3- triazoles via the three-component reaction between terminal alkynes, organic...
Application of Magnetic Chicken Feather Powder- Cu to the Click Synthesis of 1,2,3-Triazoles
activity of the prepared catalyst was studied in the synthesis of 1,2,3-triazoles
by reaction of various azides and different terminal alkynes at room temperature
under mild conditions. The reusability of the prepared nanocatalyst was
examined five...
Uniform copper nanoparticles as an inexpensive and efficient catalyst for synthesis of novel β-carbonyl-1, 2, 3-triazoles in water medium
Copper nanoparticles as an efficient, inexpensive catalyst were prepared via ball milling for synthesis of β-carbonyl 1, 2, 3-triazoles from azido alcohol by click reaction in water. An extensive range of raw materials such as sodium azide, phenacyl...
Direct access to stabilized CuI using cuttlebone as a natural-reducing support for efficient CuAAC click reactions in water
Cuttlebone@CuCl2 has efficiently catalyzed the one-pot azidonation of organic bromides, followed by
a regioselective azide-alkyne 1,3-dipolar cycloaddition (CuAAC) reaction to produce the corresponding
1,4-disubstituted 1,2,3-triazole...
