1H-Indene, 2-bromo- → HCID 23148929, compound

Participants

Reaction Steps

In a stream of nitrogen, 3.1 g (15.9 mmol) of 2-bromoindene and 1.6 g of magnesium were caused to react with each other in 50 ml of tetrahydrofuran, whereby a reaction solution containing bromomagnesium indene was obtained. The reaction solution was added dropwise to a solution prepared by dissolving 4.11 g (15.7 mmol) of (2-indenyl)(diisopropylamino)chloroborane synthesized in the above section (1) in 30 ml of tetrahydrofuran at 0° C. After the mixture had been stirred at room temperature for 4 hours, the solvent was removed by distillation, and the remainder was extracted twice with 40 ml of hexane and 10 ml of dichloromethane, whereby 6.47 g (19.0 mmol) of bis(2-indenyl)(diisopropylamino)borane as a pale yellow solid were obtained.
