1H-Indene, (1-methylethyl)- → HCID 23700053, compound

Participants

Reaction Steps

All operations are performed under an inert atmosphere and with dry, degassed solvents. A solution of 20.0 ml (32.0 mmoles) of 1.6 M butyl lithium in hexane is added to a stirred solution of 5.06 g (32.0 mmoles) of 1-isopropylindene in 100 ml of hexane at room temperature. A white precipitate appeared after 30 minutes at room temperature. Filtration after 2 days at room temperature produces 2.8 g of white solid product. The filtrate is concentrated to 20 ml and, after standing at room temperature another week, an additional 1.9 g of product is recovered for a total of 4.7 g (89 percent yield).
