FIELD: chemistry.
SUBSTANCE: invention claims improved method of obtaining metallocene halogenide compounds of the general formula (V) , where M is Zr, L is Cl, R1 is CH3, R4 is C1-C6 alkyl; R5, R6, R7, R8 and R9 are H, or C1-C20 alkyl, C7-C20 arylalkyl, or two vicinial R5, R6, R7, R8 and R9 form condensed 6-member unsaturated cycle, by the effect of halogenisation agent of the formula III, R3 xTLw, where L is Cl, T is Al, R3 is C1-20 alkyl, to a compound of the formula V, where L is substituted to L' , where L' is methyl.
EFFECT: high output and easy separation of racemic and meso-form due to high solubility of intermediate alkylated metallocene.
