Deep Eutectic Solvent Mediated Alkyne-Carbonyl Metathesis (ACM) Reaction for the Synthesis of 2H-Chromene Derivatives
2H-Chromene is an important structural motif present in many biologically active compounds, natural products and showed many other properties. Deep Eutectic Solvent (DES) an environmentally benign and alternative to the conventional organic volatile solvents has been utilized first time for the synthesis of the 2H-chromene derivatives in moderated to excellent yields. The DES is recycled for 5 tim
