1- chlorocyclohexane carboxylic acid

In the two cis/trans isomers of 4-chlorocyclohexane carboxylic acid the conformers with axial chloro atoms have conformational energies ca. 30% below those with equatorial chloro atoms (99MI7) in this connection the proportion of the trans-di-axial conformer is greater than expected. 

Cyclohexanone reacts with dichlorocarbene generated under phase transfer catalytic conditions to yield 1-chlorocyclohexane carboxylic acid [see Eq. 3.16 in Sect. 3.8].
