In this study, a sustainable and eco-friendly copper-free protocol has been developed for the regioselective synthesis of 1,4-disubstituted N -unsubstituted 1,2,3-triazoles using zinc-based heterogeneous catalyst.
Regioselective synthesis of 1,2,3-triazoles has emerged as a cornerstone modern synthetic chemistry, offering immense potential in pharmaceuticals, materials science, and functional applications. This account focuses on advancing click reaction, with majority the innovations stemming from our group’s contributions. Highlights include development novel catalytic systems, both homogeneous heterogeneous exploration copper-free photocatalytic methodologies. bridges traditional approaches,...
Exploration of Ag–Zn-based heterostructured nanoparticles as one the most efficient and promising copper-free catalysts for scalable one-pot synthesis 1,4-disubstituted 1,2,3-triazoles at room temperature.
We report for the first time hydrothermally developed copper sulfide–graphitic carbon nitride (Cu1.8S-GCN) nanocomposites as highly efficient photocatalysts azide–alkyne cycloaddition (AAC) reaction. Combining GCN with 0.8 wt % (ultralow loading) nanoparticulate Cu1.8S leads to a change in band structure, resulting enhancement of visible-light absorption and thereby mitigating problems that normally arise from conventional copper-based photocatalytic strategies. The strategy provides...
A novel and sustainable way of constructing medicinally active compounds, 4-aryl-1,2,3-(NH)-triazoles, has been developed by employing Ni(OH) 2 –ZnO nanostructured mixed crystals.
In this report, we present a sustainable, all-inorganic, lead-free double perovskite, Cu2+-doped Cs2AgBiCl6 (CABC X), designed by using simple chemical reflux approach. This material features an octahedral morphology and is explored for the first time as heterogeneous catalyst in photocatalytic oxidation of benzyl alcohol to aromatic aldehyde. Benzyl serves model reaction investigate impact Cu2+ doping on Cs2AgBiCl6, alongside reduction nitroaromatics aniline, unfolding its versatility...
Abstract In this work, we report the synthesis of nanostructured ZnC 2 O 4 .2H with irregular sheet‐like morphology using a simple hydrothermal procedure. The as‐synthesized nanocrystal (ZnC NC) is very stable and therefore, explored for first time as highly efficient recyclable catalyst azide‐alkyne cycloaddition (AAC) reaction. Our catalytic protocol amenable to variety aromatic/aliphatic azide alkyne substrates under mild reaction condition afford regioselective 1,4‐disubstituted...
