Versuchsvorschrift

To illustrate the preparation of the dithia-substituted fatty acid ethers, 5-ethylthiopentane thiol can be reacted with sodium hydride and the resulting product reacted with ethyl 5-iodovalerate to yield ethyl 6,12-dithiatetradecanoate. The ester group can then be removed by treatment with alkali metal hydroxide, e.g. NaOH, to produce the desired 6,12-dithiatetradecanoic acid.
