Abstract
One of the synthetic intermediates is used in many organic transformations. A method for highly efficient synthesis of 1,1-diacetate (3a-j) from mixture of various substituted benzaldehydes and acetic anhydride under solvent- and catalyst free using visible light irradiation (150 W tungsten lamp)has been developed. The main advantages of this protocol includes shorter reaction time, eco-friendly, mild reaction condition, easy work-up procedures, high yields of products, are the attractive features of the present methodology. All synthesized 3a-j compounds were characterized by IR, 1 H NMR and mass spectral analysis.
