FIELD: organic synthesis.
SUBSTANCE: invention relates to synthesis of organophosphorous compounds bearing P-C bond, in particular to preparation of novel 2-dichloromethylenecyclohexylphosphonic acid dichloride (formula I: comprising reaction of 2-alcoxy-7,7-dichlorobicyclo[4.1.0]heptane with phosphorus trichloride in presence of aluminum trichloride used at molar ratio 1:1:1 or 1:2:1, followed by treatment of resulting complex with water in dichloromethane.
EFFECT: increased choice of organophosphorous compounds for use as intermediates in organophosphorous synthesis.
