Catalyst-free selenylation of acylacetylenes with secondary phosphine selenides and water: A short-cut to bis(2-acylvinyl) selenides

Publication date: 15 July 2018 Source:Journal of Organometallic Chemistry, Volume 867 Author(s): Pavel A. Volkov, Nina K. Gusarova, Kseniya O. Khrapova, Anton A. Telezhkin, Nina I. Ivanova, Alexander I. Albanov, Boris A. Trofimov 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 °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%.
