A NEW AND SHORT SYNTHESIS OF 7 H-BENZO[a]CYCLOHEPTEN-7-ONE AND SOME DERIVATIVES: OXIDATION OF 7-BROMO-5H-BENZO[a]CYCLOHEPTENE

Abstract

Oxidation of 7-bromo-5H-benzo[a]cycloheptene with some oxidation reagents has been studied. Several 2,3- and 4,5-benzotropone derivatives has been obtained. The structures of the products were determined by ¹H-, ¹³C NMR data and chemical transformation.
