The interaction of TiX4 (X= Cl and Br) with 1-(trimethylsilyl) indene or 1(tributylstannyl) indene results in the formation of the crystalline trihalide complexes (rl5C9H7 )TiX3 in excellent yield. Isolation of these complexes has provided pathways for the monoalkyl complexes (TI5-C9H7 )TiX2 reaction of (r15-C9H7 )TiX3 (X = Cl and Br) withtrimethylaluminum resulted in the formation of the crystalline monomethyl complexes (Tl5C9H7 )TiX2R in good yield. Isolating these complexes free of the dimethyl derivativeproved difficult in normal alkylating solvents, but the pure monomethyl species were isolated in high yields when the reaction was performed in pentane. The chloride and bromide analogues have been stucturally characterized. Attempts to isolate thetrimethylsilylmethyl complexes (rl5-C9H7)Ti(CH2SiMe3)X2 (X = Cl and Br) as puremonoalkyl species were also successful, albeit in low yield. This set of four compounds provides a set of monoalkyl indenyl titanium species in which there are small alkyl groups or large alkyl groups as well as different halides. These complexes may prove to be excellent catalysts for the polymerization of olefins. / Department of Chemistry
