Titanium complexes containing a linked isopropyl- or benzylamido(tetramethylcyclopentadienyl) ligand C5Me4Si-Me2NR (R = iPr, CH2Ph1) and one bidentate organyl group C6H4(CH2NMe2)-2, CH2C6H4(NMe2)-2, and {η5-C5H3(CH2NMe 2)-2}Fe(η5-C5H5) were prepared by salt metathesis of the corresponding dichloro complex Ti(η5:η1-C5Me4SiMe 2NR)Cl2 with the lithium organyl. Single crystal X-ray structural analysis of Ti(η5:η1-C5Me4SiMe 2NCH2Ph)-{C6H4(CH 2NMe2)-2}Cl and of Ti(η5:η1-C5Me4SiMe 2NiPr)-{CH2C6H4(NMe 2)-2}Cl revealed the presence of intramolecu-lar coordination with square pyramidal geometry around titanium. In the ferrocenyl derivative Ti(η5;η1-C5Me4-SiMe 2NCH2Ph)[{η5-C5H 3(CH2NMe2)-2}Fe(η5-C 5H5)]Cl the NMe2 group is not bonded at the titanium atom. Ethene polymerization catalyzed by these complexes upon activation with methylaluminoxane was examined.
