✦ Synopsis

Aryl-substituted cyclohexanols were obtained by reacting 1% labelled phenyllithium with 2-and 4-phenylcyclohexanone, and 2-and 4-xenyllithium with W-labelled cyclohexanone. Heated with palladium charcoal, these yielded 14C-labelled terphenyls. I,2diphenylcyclohexanol stereo-isomers were converted into diphenylcyclohexene in order to raise the yield prior to aromatisation. The following L4C-labelled compounds have so far been prepared by this method :
