FIELD: chemistry.
SUBSTANCE: invention relates to the selective method of obtaining racemoid metallocene complexes with the general formula , where R1-R12, T, M, R15, R16 have the values indicated in the formula of the invention (cl.1). The method includes the following stages: a) deprotonation of the bonds of the formula , b) interaction of the deprotonated bond IV with the bond R7Hal2, where Hal-F, Cl, Br, I, with the subsequent repeated deprotonation with the formation of bonds of the formula and its subsequent interaction with a complex of transitive metal of the formula at t° from -78°C to +250°C. The method is carried out in one reactor, with obtaining 80%-90% of the end product in the form of racemate.
EFFECT: simplification of the process and obtaining of a product of high quality.
