Synthesis of 5‑Amino‑1H‑pyrazole‑4‑carbonitriles Using Ag/ZnO Nanoparticles as a Recyclable Catalyst.

This article discusses the synthesis of 5-amino-1H-pyrazole-4-carbonitriles using Ag/ZnO nanoparticles as a recyclable catalyst. The authors developed a one-pot procedure using environmentally friendly plant extracts to prepare the nanoparticles and optimized the reaction conditions to achieve high yields. The protocol proved to be effective for the synthesis of the desired compounds, which have various biological activities and are found in important drugs. The document also provides spectroscopic data for the synthesized compounds and acknowledges the institutions for support. [Extracted from the article]
