Abstract

q5-C5Me5) TiC13 (1) reacts with 3 equiv of lithium or Grignard reagents to form (q5-C5Me5) TiR3 (R= Me, CH2Ph, CH2SiMe3, and CsF5) and with 2 equiv to give (q5-C5Me5) TiC1R2 (R= Me, CH2Ph, and CH2SiMe3). If 1 is reacted with [O-(CH~)~ C~ H~] M~(THF), in a 2: 3 molar ratio,~-[O-(CH~)~ C~ H~]{(~~-C5Me5) Ti [o-(CH2) 2C6H4] J2 is obtained; its structure has been fully elucidated by X-ray diffraction methods. Crystals are monoclinic of space ...
