Catalyst-free selenylation of acylacetylenes with secondary phosphine SELENIDE (cas 22541-48-6)s and water: A short-cut to bis(2-acylvinyl) SELENIDE (cas 22541-48-6)s

Add time:07/15/2019    Source:sciencedirect.com

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%.
