FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing 2-phenyl-1,1,2-trichloroethyl-phosphonic acid dichloride of formula C6H5CHClCCl2P(O)Cl2 by treatment of an adduct of styrene and phosphorus pentachloride with a sulfuric acid derivative in a medium of an inert organic solvent, in order to simplify the process, the sulfuric acid derivative used is hydroxylamine sulphate and the process is carried out at room temperature.
EFFECT: development of a new method of producing 2-phenyl-1,1,2-trichloroethylphosphonic acid of formula C6H5CHClCCl2P(O)Cl2, characterized by reaction at room temperature, and also does not require use of toxic reagents.
