Naphthalene → Lithium Naphthalene

Participants

Reaction Steps

Lithium shot (1.7 grams) packed in mineral oil (Lithcoa Corporation) was magnetically stirred with naphthalene (15 grams) in dry freshly distilled tetrahydrofuran (50 milliliters) for 16 hours at 25° C. in an argon purged amber sure-seal bottle equipped with a rubber septum. The resultant dark green lithium naphthalide solution was 2 molar in concentration as determined by titration with 0.1 molar hydrochloric acid and by size exclusion chromatographic analysis of the polymeric products obtained after reaction with multiblock component monomers.
