Beschreibung
Zusammenfassung:	FIELD: organometallic synthesis. SUBSTANCE: invention provides new metallocene compounds depicted by general formula I: , in which M2 is IV group metal; R1 and R2 are halogen atoms; R3 hydrogen atom; R4 hydrogen, aryl, or two or more R4 residues together with atoms linked to them form cyclic system; R5 lower alkyl; R6 hydrogen, lower alkyl; R7 is group or wherein R11 and R12 are lower alkyls; provided that, at least one of R6 residues and also at least one of R4 and R5 residues differ from hydrogen atom. EFFECT: enlarged choice of organometallic catalysts. 9 cl, 27 ex
