## Abstract The ^47, 49^Ti chemical shifts, resonance line halfโwidths (ฮฮฝ~1/2~) and energies of the first electronic chargeโtransfer transitions $(\lambda\_{\max}^{\rm 1.CT})$ of CpโฒTiX~3~, where Cpโฒ = ฮท^5^โC~5~H~5~ (Cp), ฮท^5^โC~5~H~4~Me (MeCp), ฮท^5^โC~5~HMe~4~ (Me~4~Cp), ฮท^5^โC~5~Me~5~ (Me~5~Cp),
## Abstract Summary: The polymerization of propene in the presence of CpTi(CH~3~)~3~/B(C~6~F~5~)~3~, at low temperature, affords prevailingly syndiotactic elastomeric polypropylene. In the presence of methylalumoxane (MAO) and under the same polymerization conditions, both CpTi(CH~3~)~3~ and CpTiCl
