Naphthalen-1(2H)-one → 2-Benzyl-1,2,3,4-tetrahydronaphthalen-1-one

Participants

Reaction Steps

A Parr® hydrogenation bottle was charged with naphthalen-1-one (15 gm), ethyl acetate (150 mL) and 1 g of 10% palladium on charcoal. The mixture was hydrogenated on a Parr® shaker for about 15 hrs under 20 psi of hydrogen. The resulting mixture was filtered through a pad of Celite® and concentrated in vacuo to afford a red oil which was purified by flash chromatography (3:1 hexane/diethyl ether) to afford 14.1 gm of benzyltetralone, mp 50-51° C. Analysis calculated for C18H18O2 : 266.1302. Found: 266.1308.
