Description

In order to synthesize 6-alkyl-2-naphthols which should be expected to be intermediates of azo dyestuff for synthetic fibre as polypropylene, β-naphthyl ethylether were acylated by the reaction of Friedel Crafts using aluminium chloride and five acyl chlorides, that is, acetyl, propionyl, n-butyryl, n-valeryl and n-caproyl in nitrobenzene. Then, their carbonyl groups were reduced by the Huang-Minlon method. The final objects were obtained by boiling them with hydroiodic acid to break the ether bond. Each process resulted in good yield.
