Abstract
BENKESER et al. have reported1 that naphthalene is reduced to octalin and decalin by lithium–ethylamine; however, sodium–ethylamine was said to convert naphthalene to unidentified polymeric materials. Because of our interest in the reduction of organic compounds and of coal by metal–amine systems2, we have re-investigated the naphthalene–sodium–ethylamine reaction. The so-called polymeric material has been identified as a stereoisomer of 1,2,3,4,1′,2′,3′,4′-octahydro-2,2′-dinaphthyl, (I).
