The comparison of the rates of chromic oxydation of 2‐adamantanol, bicyclo[3.3.1]nonan‐9‐ol and cis and trans 4‐tert‐butylcyclohexanols shows that the transition state of this reaction is product‐like.
It appears that 1,3 diaxial interactions increase, according to the system, in the following order: cyclohexyl < adamantyl < bicyclo[3.3.1]nonane.
