Abstract
Starting from cis‐ and trans‐cyclohexane‐1,4‐dicarboxylic acid, cis‐and trans‐1,4‐dimethylcyclohexane are prepared in a way that leaves no doubt as to the configuration of the latter compounds.

## Abstract The preparation of pure low‐melting 4‐methylcyclohexanecarboxylic acid (m.p. 30.5‐31.5°) is described for the first time. By chemical means it is proved that low‐melting 4‐methylcyclohexanecarboxylic acid possesses the __cis__‐configuration and the high‐melting isomer the __trans__‐con
## Abstract The preparation of pure low‐melting 4‐isopropylcyclohexanecarboxylic acid (m.p. 40–41°) is described for the first time. It was isolated from mixtures of the low‐melting and the high‐melting isomer, making use of the fact that only the latter gives an inclusion compound with thiourea.
During a study of the motion of rings involved in polymer main chains, we were forced to reveal the configurations of dimethyl cyclohexanone-2,6dipropionate (k) and diethyl cyclohexane-1,3-dipropionate (2).
