Description and Uses

β-Naphthyl methyl ether has an intensely sweet, floral odor suggestive of orange blossoms. It is free from naphthol by-odor. It has a sweet, strawberry taste. This may be prepared from potassium β-naphthol and methyl chloride at 300°C; by methylation of β-naphthol with dimethyl sulfate or by direct esterification with methyl alcohol.

2-methoxynaphthalene acylation was used as a model reaction to study the catalytic benefits of delamination. It was also used to study the alkali-metal-mediated manganation (AMMMn) reactions.
