Abstract:
1. A substituted metallocene compound produced by a process comprising: (a) providing a first compound represented by the formula: wherein M is a Group 4 transition metal atom; Z is a substituted or unsubstituted cyclopenta[b]thienyl ligand that is pi-bonded to M, and wherein; Q′ is an optional bridging group that is bonded to Z and T selected from the group consisting of CH y is zero or one, Q′ is present when y is one and absent when y is zero; and T is a heteroatom with a coordination number of three from Group 15 of the Periodic Table of Elements; R″ is selected from the group consisting of 2-bromophenyl, 3-bromophenyl, 4-bromophenyl, 2,6-diisopropyl-4-bromophenyl, 2,6-dimethyl-4-bromophenyl, 2,4,6-trimethyl-3-bromophenyl, 2-bromo-4,6-dimethylphenyl, 2-bromo-4-methylphenyl, 2-bromo-3,4,6-trimethylphenyl, 2-bromo-4-fluorophenyl, 2-bromo-4,6-difluorophenyl, 2,6-dibromophenyl, 2,6-dibromo-4-methylphenyl, 2,6-dibromo-4-fluorophenyl, 2,5-dibromophenyl, and 2,4-dibromophenyl; t is the coordination number of the heteroatom T (3) where “t-1-y” indicates the number of R″ substituents bonded to T; and each X is, independently, a univalent anionic ligand, or two X are joined and bound to the metal atom to form a metallocycle ring, or two X are joined to form a chelating ligand, a diene ligand, or an alkylidene ligand; provided that Z is substituted with at least one halogen or sulfonate substituent directly bonded to any sp (b) reacting said first compound with a transfer-agent which comprises a hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl, silylcarbyl, germylcarbyl radical capable of replacing said at least one halogen or sulfonate substituent of said first compound under reaction conditions in the presence of a coupling catalyst, provided that the transfer-agent is an organometallic transfer-agent comprising an R***M′ fragment or an organic molecule R***H, where the metal M′ is selected from boron, tin, magnesium, lithium, aluminum, silicon, copper, and zinc, and R*** is selected from the group consisting of ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, isobutyl, tert-butyl, cyclopentyl, cyclohexyl, benzyl, 4-methylbenzyl, 4-methoxybenzyl, 4-trifluoromethyl, diphenylmethyl, adamantyl, cyclohexenyl, isopropenyl, 2-phenylethenyl, trimethylsilylmethyl, neopentyl, methoxymethyl, 3-methoxypropyl, dimethylaminomethyl, diphenylphosphinomethyl, 2-pyridyl, 4-pyridyl, 2-thienyl, 2-benzothienyl, 2-benzofuryl, 3-(N-methylindolyl), phenyl, 2-methylphenyl, 3-methylphenyl, 4-methylphenyl, 4-tert-butylphenyl, 2,6-dimethylphenyl, 2,6-diisopropylphenyl, 3,5-dimethylphenyl, 2,5-dimethylphenyl, 3,5-diisopropylphenyl, 3,5-di-tert-butylphenyl, 2-isopropylphenyl, 3-trifluoromethylphenyl, 4-fluorophenyl, 4-methoxyphenyl, 2-methoxyphenyl, 4-dimethylaminophenyl, 1-naphthyl, 2-naphthyl, and pentafluorophenyl.
