Versuchsvorschrift
Three grams of powdered barium hydride was stirred and reacted overnight with 2 ml. of 2-ethoxyethanol in 10 ml. of toluene, under argon atmosphere, yielding a slurry of di(2-ethoxyethoxy)-barium in toluene. To the slurry was added 10 ml. of a 1.7 molar solution of n-butyl-lithium in n-pentane. The mixture was stirred for 3 hours at room temperature, during which time a reaction ensued between the di(2-ethoxyethoxy)-barium, the n-butyl-lithium, and the toluene to give a partly hydrocarbon-soluble, lithium-containing, organometallic product having tolyl functionality.
