Hydrogen Sulfide → 9,9'-Sulfanediyldianthracene

Participants

Reaction Steps

Hydrogen sulphide is passed into a solution of 20 g (0.08 mole) of 9-bromoanthracene in decahydronaphthalene at a temperature of 180° C for 14 hours, the solvent is separated by filtration, the residue is recrystallized from toluene to obtain 8.5 g (63.3 percent by weight) of di(9-anthryl) sulphide. This is a yellow crystalline substance melting at 257° C.
