FIELD: organic chemistry. SUBSTANCE: invention proposes metallocenes with benzofused derivatives of indenyl as ligands, method of their synthesis and use as catalysts. Very effective catalyst system for olefin polymerization consists of cocatalyst, preferably, aluminium oxamine and metallocene of the formula (I): 
where M1 means preferably Zr or Hf; R1 and R2 - halogen or alkyl; R3 - alkyl; R4-R10 - alkyl or hydrogen and R11 - (substituted) alkylene or heteroatomic bridge. EFFECT: improved method of synthesis and producing, enhanced effectiveness of catalyst. 12 cl, 3 tbl
