실험 절차

Analogously to Example 19, 2.5 g (0.010 mol) of bis(cyclopentadienyl)titanium dichloride and 4.9 g (0.022 mol) of 1-[3-(2,4-difluorophenyl)propyl]-1H-pyrrole are reacted with 0.022 mol of lithium diisopropylamide solution. The brown-orange oil is purified by means of flash chromatography using hexane/ethyl acetate (9:1) as solvent. 2.3 g of an orange glassy resin are obtained.
