The addition of hydrogen bromide to cis-bicyclonona-3,7-diene takes place preferentially but not selectively at the double bond of the six-membered ring.In the case of gaseous hydrogen bromide only bromobicyclononenes are formed, but with 48percent aqueous hydrobromic acid the reaction is accompanied by transannular cyclization and by the formation of endo- and exo-5-bromobrexanes (16-20percent).A method is proposed for the production of brexan-5-one.
