Abstract

Initially, we chose toluene and allylic acetate as the model substrates to optimize suitable conditions for this reaction (Table [¹] ). It was found that the oxidants, catalysts, and solvent affected the reaction efficiency critically. The oxidant AgOAc was better than others such as Ag 2 CO 3 , Ag 2 O, Ag 2 SO 4 , benzoquinone (BQ), and O 2 (Table [¹] , entries 1-10). The desired product was obtained in good yield by using a mixed solvent of 5% DMSO in toluene (Table [¹] , entry 11). Other ...
