  New syndiospecific catalysts for styrene polymerization

  摘要：

  (Eta5-Tetramethylcyclopentadienyl)-, (eta5-tetraphenylcyclopentadienyl)-, (eta5-(diphenylphosphi-no)tetramethylcyclopentadienyl)-, and (eta5-(trimethylsilyl)tetramethylcyclopentadienyl)titanium triisopropoxide have been synthesized and characterized. Their catalytic activities for syndiospecific styrene polymerization have been compared with the reference compound (eta5-cyclopentadienyl)titanium triisopropoxide. (Eta5-Tetramethylcyclopentadienyl)titanium triisopropoxide is the best catalyst precursor, giving rise to catalysts having the highest activity to produce polystyrene with the highest syndiotactic yield and molecular weight.

  The reactivity of the monocyclopentadienyl complex [(C5H4PPh2)U(BH4)3] and of its borane adduct [(C5H4PPh2·BH3)U(BH4)3] strongly suggest that in solutions these complexes are in equilibrium with the biscyclopentadienyls [(C5H4PPh2)2U(BH4)2] and [(C5H4PPh2·BH3)2U(BH4)2] and uranium tetraborohydride [U(BH4)4] which is the most reactive species in such systems.

• Synthesis of bent titanocene metalloligands with the (diphenylphosphino)tetramethylcyclopentadienyl moiety. X-ray structure of [(η5-C5Me42)2TiCl2]Mo(CO)4

  The reactions of lithium(diphenylphosphino)tetramethylcyclopentadienide with CpTiCl3 and secondly with TiCl3 followed by CCl4 oxidation lead to the formation of two titanocene phosphines: (eta-5-C5H5)[eta-5-C5Me4P(C6H5)2]TiCl2 (2) and [eta-5-C5Me4P(C6H5)2]2TiCl2 (3), respectively. The metalloligand 3 reacts readily with Mo(CO)4cod, Mo(CO)5THF and Mo(CO)6 to give in each case [(eta-5-C5Me4PPh2)2-TiCl2]Mo(CO)4 (6) as a sole product. The structure of 6 has been determined by X-ray diffraction. Crystal data: P1 approximately, a = 11.716(1), b = 11.753(2), c = 16.110(2) angstrom, alpha = 99.06(1), beta = 92.61(1), gamma = 104.20(1)-degrees, Z = 2. The molybdenum-titanium distance of 5.194(1) angstrom rules out any metal-metal interaction. The chlorine substitution reactions by CO in 2 and 3 and by thiolate group (pH3C-C6H4-S) in 6 are reported.
