FIELD: chemistry.
SUBSTANCE: chemistry of organophosphorus compounds with a P–C bond, namely a method for producing styrylphosphonic acid dichloride of the formula C6H5CH=CHP(O)Cl2 by decomposition of the adduct of styrene and phosphorus pentachloride with an acid salt in an inert organic solvent, characterized in that the sodium percarbonate is used as the acid salt and the process is carried out at room temperature.
EFFECT: new method for producing styrylphosphonic acid dichloride with high yield and purity, which can be used as an intermediate product of organophosphorus synthesis.
