Herein, we present a sustainable and atom-economical approach for the synthesis of quinazolinones via acceptorless dehydrogenative coupling (ADC) using earth-abundant Co-salt, (CoCl) as the catalyst under neat condition. This method is distinguished by its green credentials, like, solvent-free, microwave-assisted heating, cost-effective, use of renewable alcohols, and generating only H and water as byproducts. Remarkably, this protocol achieves quinazolinone synthesis without the need for external ligands, oxidants, or additional additives.

A new nanocomposite based on alginate microbeads impregnated with novel strontium-aluminum layered double hydroxide (Sr-Al LDH) incorporated with choline chloride-urea deep eutectic solvent (ChCl-U DES) was introduced. The microbeads and LDH were characterized by adsorption/desorption isotherms, Fourier-transform infrared spectroscopy, SEM, and x-ray diffraction. The adsorbent was employed for determining penicillin G (PENG) using dispersive solid-phase extraction prior to HPLC analysis.

Four air-stable one-dimensional copper(II) coordination polymers (-) with azide linkers were synthesized using tridentate NNS and NNN ligands. Single-crystal X-ray diffraction (XRD) analysis confirmed the molecular structures of , , and . In the presence of TEMPO, all four coordination polymers demonstrated effective catalytic activity for the selective aerobic oxidation of veratryl alcohol, a biomass model compound, under base-free conditions.
