Claim:
A process for producing an alkoxy-titanium complex of formula (2): wherein A, R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , and R 10 each denotes the same meaning as described below; R 11 and R 12 are the same or different and denote a C 1-20 alkyl group which may be substituted by halogen, a C 7-20 aralkyl group which may be substituted by halogen, or a C 6-20 aryl group which may be substituted by halogen, and R 11 and R 12 may be bonded to form a ring, which comprises reacting a magnesium compound of formula (3): R 13 MgX 3 (3) wherein R 13 denotes a C 1-20 alkyl group, a C 6-20 aryl group, or a C 7-20 aralkyl group, and X 3 denotes halogen, with an alcohol of formula (4): R 14 OH (4) wherein R 14 is the same as R 11 or R 12 , and reacting the resulting magnesium alkoxide with a titanium halide complex of formula (1): wherein A denotes a Group 14 element of the periodic table; R 1 , R 2 , R 3 , and R 4 are the same or different and denote a hydrogen atom, halogen, a C 1-20 alkyl group which may be substituted by halogen, a C 6-20 aryl group which may be substituted by halogen, a C 7-20 aralkyl group which may be substituted by halogen, a silyl group substituted by C 1-20 hydrocarbon which may be substituted by halogen, a C 1-20 alkoxy group which may be substituted by halogen, a C 6-20 aryloxy group which may be substituted by halogen, a C 7-20 aralkyloxy group which may be substituted by halogen, a silyloxy group substituted by C 1-20 hydrocarbon which may be substituted by halogen, an amino group substituted by C 1-20 hydrocarbon which may be substituted by halogen, a phosphino group substituted by C 1-20 hydrocarbon which may be substituted by halogen, or a thio group substituted by C 1-20 hydrocarbon which may be substituted by halogen; R 5 , R 6 , R 7 , R 8 , R 9 , and R 10 are the same or different and denote a hydrogen atom, halogen, a C 1-20 alkyl group which may be substituted by halogen, a C 1-20 alkoxy group which may be substituted by halogen, a C 6-20 aryl group which may be substituted by halogen, a C 6-20 aryloxy group which may be substituted by halogen, a C 7-20 aralkyl group which may be substituted by halogen, a C 7-20 aralkyloxy group which may be substituted by halogen, a silyl group substituted by C 1-20 hydrocarbon which may be substituted by halogen, or an amino group substituted by C 1-20 hydrocarbon which may be substituted by halogen; pairs of R 1 with R 2 and R 3 with R 4 are bonded to form fluorene, which may be substituted, and R 5 and R 6 may be bonded to form a ring; neighboring groups among R 7 , R 8 , R 9 , and R 10 may be arbitrarily bonded to form a ring, and X 1 and X 2 independently denote any halogen atom.
