In a previous Sotel the migration of terminal double bond under the strongly alkaline condition was described. When 7-keto-16-heptadecenoic acid was subjected to the Huang- Jlinlon reduction, an isomeric mixture of 15heptadecenoic acids was obtained. Similar result was also reported by Hiinig and Eckart, 2 and according to them IBheptadecenoic acid could be obtained by substituting triethanolaminea for diethylene glycol as the solvent.
