Abstract
Improved preparations of cyclo-octane-1,5-dione and 1,5-dimethlenecyclo-octane are described. The diene reacts with bromine and strong acids to give 1,5-disubstituted derivatives of bicyclo[3.3.1]nonane in high yield; contrary to an earlier report, the bicyclo[3.3.2.]decane skeleton is not formed in the latter case.Keywords
