Procedure

In a 500-mL flask were placed 32.62 g of technical grade indene (92.5 wt %) and 165 mL of diethyl ether. To this stirred solution were added 99.5 mL of 2.5 M n-BuLi (in hexanes) over 45 minutes. The reaction was exothermic and the solvent refluxed spontaneously and was returned to the reaction by an ice-water cooled condenser. A clear orange solution of lithium indenide was obtained.
