Condensation reactions of 2,5-dimethoxytetrahydrofuran with p-substituted phenols and 2-naphthol in trifluoroacetic acid produce 1,1,4,4-tetrakis(2-hydroxyphenyl)butane type compounds and 1,2-bis(1,3-dibenzo[a,j]xanthyl)ethane in good yields.
在三氟乙酸中,2,5-二甲氧基四氢呋喃与对取代酚和 2-萘酚发生缩合反应,生成 1,1,4,4-四(2-羟基苯基)丁烷类化合物和 1,2-双(1,3-二苯并[a,j]黄原酸基)乙烷,收率良好。
