摘要：

Bromination of 3-aryl-4-acetylsydnones with alkali bromide and sulfuric acid yielded 3-aryl-4-dibromoacetylsydnones (R=H, Me, Cl, NO2) and 3-(3-bromoaryl)-4-dibromoacetylsydnones (R=OH, OMe, OEt) in good yields. The resultant dibromoacetylsydnones were converted to the corresponding 3-arylsydnones with alcoholic NaOH solution.
