  Reactions of sodium selenide with ethynyl and bromoethynyl ketones: Stereo- and regioselective synthesis of functionalized divinyl selenides and 1,3-diselenetanes

  摘要：

  A method for the preparation of 2,4-dimethylene-1,3-diselenetanes based on the novel reaction of sodium selenide with bromoethynyl ketones has been developed. New functionalized divinyl selenides have been obtained by regio- and stereoselective addition of sodium selenide to ethynyl ketones. (C) 2009 Elsevier B. V. All rights reserved.

  Secondary phosphine selenides react with acylacetylenes in water to form bis(2-acylvinyl) selenides. The reaction proceeds without catalyst and organic solvent under mild conditions (70-72 degrees C, 3 h), the corresponding divinyl selenides being isolated as a mixture of (Z, Z)-and (E, Z)-isomers in a yield of up to 78%.
