FIELD: chemistry.
SUBSTANCE: organic complex of palladium - tris(dibenzylidene acetone)palladium reacts with white phosphorus in a tetrahydrofuran medium. The palladium phosphides formed undergo hydrolysis at temperature 20-70°C with degassed water. Molar ratio of reactants palladium complex: white phosphorus: water is equal to 1:(1-20):(12-480). The end product is extracted by separating the residue and evaporating the filtrate in a vacuum.
EFFECT: method is environmentally safe, selective and enables to obtain phosphorous acid from simple and readily available reactants with high output.
