Chalcogenopyranones from disodium chalcogenide additions to 1,4- pentadiyn-3-ones. The role of enol ethers as intermediates

10.1002/jhet.5570360322

The research focuses on the synthesis of 4H-chalcogenopyran-4-ones using disodium chalcogenides and enol ethers derived from 1,4-pentadiyn-3-ones. Key chemicals involved include diynones such as 1,5-diphenyl-1,4-pentadiyn-3-one (2a), 1,5-di-tert-butyl-1,4-pentadiyn-3-one (2b), and 1,5-di-(4-N,N-dimethylaminophenyl)-1,4-pentadiyn-3-one (2c), which are reacted with disodium chalcogenides like disodium sulfide, disodium selenide, and disodium telluride. Enol ethers 9 are formed as intermediates from the addition of ethanol to diynones in sodium ethoxide/ethanol, and these enol ethers react with disodium chalcogenides to yield 2,6-disubstituted chalcogenopyranones with high selectivity. The study also examines the addition of hydrogen sulfide to diynones and the role of intermediates in the formation of chalcogenopyranones and dihydrochalcogenophenes. The research aims to improve the synthesis of chalcogenopyranones, which have applications in various fields including as electron-accepting materials in electrophotography and as heat-generating elements in optical recording.
