Abstract

Abstract A convenient synthesis of vinylphosphonates which involves addition of elemental selenium to phosphonate carbanions followed by alkylation and selenoxide elimination is described. A general approach to 1, 4-dicarbonyl systems based on diethyl α- methylthiovinylphosphonate is also reported.
