Sodium borohydride → Ethyl2-(1,2-dihydro-1-acenaphthylenyl)acetate

Participants

Reaction Steps

55 mg of PdCl2 in 5 ml of methanol are treated with 25 mg of sodium borohydride. After 15 minutes' stirring, the compound obtained in Step B (1 g, 4.20.10−3 mol), diluted with methanol (25 ml), is added. The mixture is purged with argon and placed under a hydrogen atmosphere. After 2 hours 30 minutes' hydrogenation, the reaction mixture is filtered over Celite, rinsed and then evaporated under reduced pressure.
