Description
Summary:One pot multi‐component, simple and energy efficient protocol for the synthesis of 2,4,6‐triaryl pyridines mediated via a unique blend of deep eutectic solvents (DES) and concentrated solar radiations (CSR) has been developed. The choline chloride: malonic acid DES employed herein plays a dual role of catalyst and solvent. The employment of CSR is found to be superior to thermal methods in terms of time and energy conservation. Up to 66% of energy conservation is observed following the developed protocol. The amalgamation of DES and renewable energy (CSR), easy synthesis and workup procedure renders the protocol energy efficient and environmentally benign. One pot multi‐component, a simple and energy efficient protocol for the synthesis of 2,4,6‐triaryl pyridines mediated via a unique blend of deep eutectic solvents (DES) and concentrated solar radiations (CSR).
