Abstract:
1. A process for producing an organotitanium compound which comprises reacting an acetylene compound represented by the formula (8) below in the presence of a titanium compound represented by the formula (2) below and a Grignard reagent represented by the formula (3) below with a compound represented by the formula (5) below, thereby giving said titanium compound represented by the formula (9) and/or (10) below where R where X 1 , X 2 , X 3 , and X 4 denote mutually independently a halogen atom, C 1-6 alkoxy group {which may be substituted with a phenyl group (which may be substituted with a C 1-6 alkyl group, C 1-6 alkoxy group, or phenyl group), or a naphthyl group)}, phenoxy group (which may be substituted with a C 1-6 alkyl group, C 1-6 alkoxy group, or phenyl group), or naphthoxy group where R denotes a C 2-8 alkyl group having a hydrogen atom at the β position, and X 5 denotes a halogen atom where R 5 denotes a hydrogen atom, C 1-20 alkyl group, or phenyl group (which may be substituted with a C 1-6 alkyl group, C 1-6 alkoxy group, C 1-6 alkoxycarbonyl group, C 1-6 alkylaminocarbonyl group, or di-C 1-6 -alkylaminocarbonyl group), Z denotes CR′ (where R′ denotes a hydrogen atom or C 1-20 alkyl group) or a nitrogen atom; X 6 denotes a halogen atom, C 1-6 alkoxy group {which may be substituted with a phenyl group (which may be substituted with a C 1-6 alkyl group, C 1-6 alkoxy group, and phenyl group), or naphthyl group}, phenoxy group (which may be substituted with a C 1-6 alkyl group, C 1-6 alkoxy group, or phenyl group), naphthoxy group, SO n R 6 {where R 6 denotes a C 1-6 alkyl group or phenyl group (which may be substituted with a halogen atom or C 1-6 alkyl group) and n denotes 1 or 2}, OSO 2 R 6 (where R 6 is defined as above), or OP(O)(OR 13 ) 2 group (where R 13 denotes a C 1-6 alkyl group); and m denotes 0 or 1 where R 1 , R 4 , R 5 , Y, Z, X 6 , and m are defined as above; and X p and X q denote any of X 1 ˜X 4 (which are defined as above).
