2-Bromoindene (4.0 g, 0.02 mol.) was dissolved in 4 ml of tetrahydrofuran and added dropwise to a mixture consisting of magnesium (0.73 g, 0.03 mol.) and dichlorodimethylsilane (5.0 g, 0.04 mol.) in 4 ml of tetrahydrofuran. During the addition, the solution boiled slightly. After 15 hours' stirring, the volatile constituents were removed under an oil pump vacuum, and 40 ml of n-pentane were added to the residue. The resulting magnesium salt was filtered off with suction. The solvent was removed under an oil pump vacuum to yield 4.6 g (95%) of chloro-2-indenyl-dimethylsilane in the form of a colorless oil.
