Abstract: PURPOSE:To obtain an olefin polymn. catalyst which gives a (co)polymer having a narrow mol.wt. distribution, a narrow compsn. distribution, a high mol.wt., and a low m.p. by selecting a specific transition metal compd. CONSTITUTION:A transition metal compd. is selected which is represented by the formula [wherein M is a transition metal of the group IVa. Va, or VIa; R and R are each halogen, a 1-2OC optionally halogenated hydrocarbon group or an Si-, O-, S-, N-, or P-contg. group; R is a 2-20C hydrocarbon group; X and X are each H, halogen, a 1-2OC optionally halogenated hydrocarbon group, or an O- or S-contg. group; and Y is a divalent 1-20C optionally halogenated hydrocarbon group, a divalent Si-, Ge-, or Sn-contg. group, 0, CO, S, SO, S0 , NR , P(R ), P(0)(R ), BR , or AlR (wherein R is H, halogen, or a 1-20C optionally halogenated hydrocarbon group)].

Abstract: PURPOSE:To produce a l-indanone compound useful e.g. as a starting substance for an olefin polymerization catalyst by a single-stage reaction in high yield by reacting a specific benzene derivative with a methacrylic acid halide in the presence of a Lewis acid or a strong acid. CONSTITUTION:A 1-indanone compound of formula Ia and/or formula Ib is produced by reacting a compound of formula II [R to R are each H, a halogen, a 1-20C (halogenated)hydrocarbon group, a silicon-containing group, an oxygen- containing group, an S-containing group, an N-containing group or a P- containing group or adjacent groups are bonded with each other to form a ring] with a compound of formula III (R is same as R to R ; X is a halogen) in the presence of a Lewis acid or a strong acid. The Lewis acid is preferably aluminum trichloride, tin tetrachloride, etc., and the strong acid is preferably trifluoromethanesulfonic acid, hydrogen fluoride, etc. The compound of formula II is e.g. p-cymene and the compound of formula Ia or formula Ib is e.g. 2,4- dimethyl-7-isopropyl-1-indanone or 2,7-dimethyl-4-isopropyl-1-indanone.
