Authors: ARİF DAŞTAN, Y. KEMAL YILDIZ, CAVİT KAZAZ, METİN BALCI

Abstract: The oxidation of 8-bromo-5H-benzo[a]cycloheptene with some oxidation reagents was studied. 2,3- and 4,5-benzotropone derivatives were obtained. The structures of the bromobenzotropones were determined by ^{1}H- and ^{13}C-NMR data.

Keywords: Tropone, benzotropone, bromobenzotropone, selenium dioxide and chromium trioxide oxidation.
