Naphthalene → Naphthalene potassium

Temperature

-111 °C

A solution of potassium naphthalene was prepared from potassium (110 mg) and naphthalene (400 mg), in tetrahydrofuran (40 ml). This was added to a suspension of [(Ph2CH3P)2RuCl]2H (780 mg) in 40 ml of tetrahydrofuran, cooled to -111° C. The reducing metal arene solution was added slowly, and the reaction mixture, at -111° C. was vigorously agitated throughout the addition. The solution was then warmed to -80° C., and stirred for 18 hours at this temperature, then slowly warmed to room temperature. The resultant solution was filtered and evaporated to dryness giving a dark brown solid. The latter gave a broad metal-hydride absorption band in the infrared region at 1800 cm-1. On the basis of the elemental analyses of this crude product, we regard the composition as being [(Ph2CH3P)3RuH]-K+.
