FIELD: chemistry.
SUBSTANCE: invention relates to a method for synthesis of dichloranhydride of 2-(2,3-dichloropropoxy)ethenyl phosphonic acid of formula (1), which can be used in organic synthesis: ClCH2CHClCH2OCH=CHP(O)Cl2, 1. The proposed method involves reaction of vinyl glycidyl ether with phosphorus pentachloride in molar ratio 1:2 in a medium of an inert organic solvent at temperature 0-20°C and subsequent treatment of the formed adduct with acetone.
EFFECT: design of a method for synthesis of an organic synthesis intermediate product.
