主 题：Amino acid ionic liquid Baeyer-Villiger oxidation Cyclic ketone Lactone
摘 要：A series of amino-acid-based ionic liquids was synthesized via one-step protonation of the corresponding L-amiiio acid by utilizing an array of proton *** catalytic activity of the amino-acid-based ionic liquids for the Baeyer-Villiger oxidation of cyclic ketones was investigated using cyclopentanone as a model ***-based ionic liquid[ProH]CF3SO3 was shown to exliibit thebest catalytic *** reaction condition was optimized to give the following reagent ratio of h(cyclopentanone):n(catalyst):w(H2O2)=1:0.06:4,60℃and 6 *** the optimum conditions,the conversion of cyclopentanone was 96.57%and the selectivity forδ-valerolactone was 73.01%.The catalytic activity was shown to be constant after 4 cycles.A simple treatment was allowed for the recover and the reuse of[ProH]*** successful utilization of[ProH]CF3SO3 to catalyze a host of cyclic ketones via Baeyer-Villiger oxidation clearly demonstrated the capacity of[ProH]CF3S03 to tolerate variation in the substrate.
