Participants

Reaction Steps

Ammonia was condensed (ca 200 ml) into 150 ml of dry diethylether in a 3-necked flask, with external cooling. Then 9.0 g (0.0256 mole) of 2,5-dibenzylmercapto-p-benzoquinone was dissolved into the liquid. Sodium (5.9 g, 0.256 mole) cut into fine pieces was added portionwise with efficient stirring. After stirring for an additional 2.5 hours, abs. ethanol (20 ml) was added and the ammonia was evaporated. Water (170 ml) was added to the reaction product and it was extracted with 2×30 ml of ether. The aqueous phase was then acidified to pH 1-2, with conc. hydrochloric acid, and extracted with 3×80 ml of ether. The ether extracts were collected, dried (Na2SO4), the solvent evaporated leaving a fluffy light brown glistening residue, 4.3 g (90%).
