Abstract:
A process for producing an organotitanium compound which comprises reacting an acetylene compound represented by the formula (1) 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 an acetylene compound represented by the formula (4) below and further reacting with a compound represented by the formula (5) below, thereby giving said titanium compound represented by the formula (6) and/or (7) below where R1 and R2 denote mutually independently a C1-20 alkyl group {which may be substituted with a C1-6 alkoxy group (which may be substituted with a phenyl group) or OSiR7R8R9 (where R7, R8, and R9 denote mutually independently a C1-6 alkyl group or phenyl group)}, C3-20 alkenyl, C1-6 alkoxy group, C1-6 alkoxycarbonyl group, C1-6 alkylaminocarbonyl group, di-C1-6-alkylaminocarbonyl group, phenyl group (which may be substituted with a C1-6 alkyl group, C1-6 alkoxy group, C1-6 alkoxycarbonyl group, C1-6 alkylaminocarbonyl group, or di-C1-6-alkylaminocarbonyl group), furyl group, amino group, SiR7R8R9 (where R7, R8, and R9 denote mutually independently a C1-6 alkyl group or phenyl group), or SnR10R11R12 (where R10, R11, and R12 denote mutually independently a halogen atom, C1-6 alkyl group, or phenyl group) TiX1X2X3X4â€ƒâ€ƒ(2) where X1, X2, X3, and X4 denote mutually independently a halogen atom, C1-6 alkoxy group {which may be substituted with a phenyl group (which may be substituted with a C1-6 alkyl group, C1-6 alkoxy group, or phenyl group) or naphthyl group}, phenoxy group (which may be substituted with a C1-6 alkyl group, C1-6 alkoxy group, or phenyl group), or naphthoxy group RMgX5â€ƒâ€ƒ(3) where R denotes a C2-8 alkyl group having a hydrogen atom at the &bgr; position, and X5 denotes a halogen atom where R3 and R4 denote mutually independently a hydrogen atom, C1-20 alkyl group, C1-6 alkoxy group, C1-6 alkoxycarbonyl group, C1-6 alkylaminocarbonyl group, di-C1-6-alkylaminocarbonyl group, phenyl group (which may be substituted with a C1-6 alkyl group, C1-6 alkoxy group, C1-6 alkoxycarbonyl group, C1-6 alkylaminocarbonyl group, or di-C1-6-alkylaminocarbonyl group), furyl group, amino group, SiR7R8R9 (where R7, R8, and R9 are defined as above), or SnR10R11R12 (where R10, R11, and R12 are defined as above) where R5 denotes a hydrogen atom, C1-20 alkyl group, or phenyl group (which may be substituted with a C1-6 alkyl group, C1-6 alkoxy group, C1-6 alkoxycarbonyl group, C1-6 alkylaminocarbonyl group, or di-C1-6-alkylaminocarbonyl group); Z denotes CRâ€² (where Râ€² denotes a hydrogen atom or C1-20 alkyl group) or a nitrogen atom; X6 denotes a halogen atom, C1-6 alkoxy group {which may be substituted with a phenyl group (which may be substituted with a C1-6 alkyl group, C1-6 alkoxy group, or phenyl group) or naphthyl group}, phenoxy group (which may be substituted with a C1-6 alkyl group, C1-6 alkoxy group, or phenyl group), naphthoxy group, SOnR6 group {where R6 denotes a C1-6 alkyl group or phenyl group (which may be substituted with a halogen atom or C1-6 alkyl group) and n denotes 1 or 2}, OSO2R6 group (where R6 is defined as above), or OP(O)(OR13)2 group (where R13 denotes a C1-6 alkyl group); and m denotes 0 or 1 where R1ËœR5, Z, X6, and m are defined as above; and Xp and Xq denote any of X1ËœX4 (which are defined as above).
