Dimethyl sulfoxide-hydrobromic acid as a novel reagent for convenient oxidation on a preparative scale of stilbenes and some derivatives of diphenylethane to benzils
摘要:
We have found that the systems HBr-H2O2-DMSO and HBr-DMSO are mild and selective reagents for the high-yield oxidation of the C = C bond in stilbenes to benzils. These reagents also successfully oxidate 1,2-diphenyl-1,2-dibromoethane and a number of its derivatives to benzils. We have evaluated the preparative potentialities of the novel reagents.
