During the acylation of 2,7-dimethoxynaphthalene with acetyl chloride in the presence of boron trifluoride etherate 1-acetyl-2,7-dimethoxynaphthalene is formed.In polyphosphoric acid the main product is its 3-isomer, whereas in nitrobenzene and dichloroethane in the presence of aluminium chloride a mixture of both compounds is formed.Further acetylation of these ketones leads to 1,8- and 1,6-diacetyl-2,7-dimethoxynaphthalene respectively.The results are explained by the instability of 1-acetyl-2,7-dimethoxynaphthalene in the presence of strong protic acids.
