Tin and Copper Dispersed on Metal-organic Framework as a New Fantastic Catalyst for Aerobic Baeyer-Villiger Oxidation of Cyclohexanone

Baeyer-Villiger (B-V) oxidation reaction is one of the most important reactions in the field of organic chemistry, in which ketones become lactones or esters, which are valuable intermediates in a wide range of chemical industries such as dyestuff, perfume, pharmaceutical, detergent, agriculture, and polymer [1-3].Caprolactone is one of the products produced by this reaction and plays a major role in the pharmaceutical and medical fields as a monomer for the preparation of biodegradable polymers of poly-caprolactone [4,5].Hence, the development of efficient and selective catalysts for oxidative Baeyer-Villiger reaction, economically feasible and with the least amount of environmental damage, is one of the most important challenges in the present era. In this study, metal-organic frameworks (MOFs) containing two tin and copper metalsalts have been used for the first time as efficient catalysts for the Baeyer-Villiger (B-V) oxidation reaction of cyclohexanone.The results showed a synergistic effect on theselectivity and catalyst efficiency, resulting in the simultaneous presence of two copper and tin metal in the MOF.In addition, these catalysts can berecovered during consecutive cycles without notable loss in their catalytic activity
