실험 절차

Potassium cyclooctadienide (3.42 g, 23.4 mmols) dissolved in about 50 mL of THF was added to a solution of (tetramethylcyclopentadienyl)chloro-dimethylsilane (5.02 g, 23.4 mmols) in about 80 mL of THF at about 25° C. A precipitate formed and the reaction mixture was stirred for about 16 hours at about 25° C., after which time the reaction mixture was filtered and the solvents removed under reduced pressure. The residue was extracted with hexane and filtered. The solvents were again removed under reduced pressure leaving the desired isomeric product comprising (tetramethylcyclopentadienyl)(cylcoocta-2,7-dien-1-yl)dimethylsilane and (tetramethylcyclopentadienyl)(cylcoocta-2,4-dien-1-yl)dimethylsilane.
