A Robust Nanocatalyst Incorporating Multi-Walled Carbon Nanotubes Infused with Magnetic Nanoparticles and Biguanide-Silver Nanoparticles for Multicomponent Synthesis of Benzopyrano-Pyrimidines.

ABSTRACT: A highly efficient and environmentally friendly synthetic method has been developed for the preparation of benzopyrano-pyrimidines using multi-walled carbon nanotubes/magnetic nanoparticles-Biguanide-Ag NPs as a heterogeneous nanocatalyst in choline chloride-urea (ChCl-Urea) deep eutectic solvent. This approach offers numerous advantages, including high isolated yields (86-99%) and short reaction times (10-70 min), along with broad substrate compatibility for both electron-donating and electron-withdrawing functional groups. The method exhibits excellent catalytic efficiency, with high turnover numbers and turnover frequencies, even at low catalyst loading. The use of ChCl-Urea as a green, biodegradable, and nonvolatile solvent aligns with sustainable chemistry principles and allows for ea
