Abstract

Secondary phosphine chalcogenides add to benzoylacetylene in KOH-THF suspension (the addition proceeds solely to the triple bond) to form depending on the PH-addend nature and reaction conditions either α,β- or β,β-diadducts, regardless of reactant ratio.

Keywords: Secondary phosphine oxides, secondary phosphine sulfides, benzoylacetylene, nucleophilic αβ- and β,β-addition
