FIELD: chemistry. ^ SUBSTANCE: present invention relates to an improved method for racemoselective preparation of ansa-metallocene complexes, as well as subsequent conversion of these complexes to ansa-metallocenes, transition metal compounds, as well as their use in racemoselective preparation of ansa-metallocenes, ansa-metallocene complexes and their use as components of catalyst systems for polymerisation of unsaturated olefin compounds. ^ EFFECT: method is cheap and has advantages with respect to environment-related properties of the used materials. ^ 2 cl, 3 ex |
