    Abstract: PROBLEM TO BE SOLVED: To obtain a new transition metal compound comprising a specific transition metal compound having monocyclopentadienyl compound as a ligand and useful as a catalyst effective in production of a polyolefin by combining with a cocatalyst such as aluminoxane. SOLUTION: This new transition metal compound is represented by formula I [M is a metal of group IIIb, IVb or Vb in the periodic table; R to R are each H, a halogen, a group including a 1-10C hydrocarbon, SiR 3 (R is a halogen, a 1-10C alkyl or a 6-10C aryl), etc.; Y is H, a group including a 1-40C hydrocarbon, OH, a halogen, etc.; (k) is an integer corresponding to the value of the valence number of the transition metal M1 minus 2; A is a bridge; R is H, a halogen, a group including a 1-40C hydrocarbon, SiR 3 , etc.; X is a metal of group Va or VIa in the periodic table] and acts as a catalyst useful for preparation of a polyolefin. The compound is obtained by reacting a compound of formula II (R is H, a halogen or a group including a 1-40C hydrocarbon) with a nucleophilic or a basic compound and thereafter reacting the product with a metal compound.
