Heating of 2-ethoxynaphthalene with 1,3,5-triazine or 2,4,6-trimethyl-1,3,5-triazine in polyphosphoric acid leads to the corresponding products of mono- or diacylation: 2-ethoxy-naphthalene-1-carbaldehyde, 1-acetyl-2-ethoxynaphthalene, 2-ethoxynaphthalene-1,8-dicarb-aldehyde, and 1,8-diacetyl-2-ethoxynaphthalene in ∼60–80% yield.
将 2-乙氧基
萘与
1,3,5-三嗪或
2,4,6-三甲基-1,3,5-三嗪在多
磷酸中加热,会产生相应的单酰化或二酰化产物:2-ethoxy-naphthalene-1-carbaldehyde, 1-acetyl-2-ethoxynaphthalene, 2-ethoxynaphthalene-1,8-dicarb-aldehyde, and 1,8-diacetyl-2-ethoxynaphthalene 的产率在 60-80% 之间。
