Potassium Iodide → 1,1'-(Fluoranthene-3,9-diyl)bis[4-(diethylamino)butan-1-one]--hydrogen chloride (1/2)

Participants

Reaction Steps

A solution of 15.0 g (0.037 mole) of 3,9-bis(4-chlorobutyryl)fluoranthene, 100 ml of diethylamine, 2.0 g of potassium iodide and 100 ml of tetrahydrofuran (THF) is heated at reflux with stirring for 3 days and filtered. The filtrate is poured onto ice water and the oil which separates is decanted and dissolved in ether. The ether solution is washed with a water-saturated sodium chloride solution, dried over magnesium sulfate and filtered. The filtrate is acidified with ethereal HCl, and the resulting precipitate is recrystallized twice from methanol-butanone to yield 3,9-bis(4-diethylaminobutyryl)fluoranthene dihydrochloride. M.P. 236°-239°C.
