Abstract
Enyne‐hydrocarbons, ‐alcohols and ‐ethers with the systemcan be converted into the isomers with a terminal acetylenic group, by treating them with an excess of potassium amide in liquid ammonia and hydrolysing the reaction mixture thus formed. In most cases yields are excellent.Enyne thioethers RCC‐CHCH‐SC2H5(R alkyl) undergo an elimination of ethanethiol under these conditions. Hydrolysis affords the 1,3‐diynes RCC‐CCH in very good yields.Keywords
