In the presence of catalytic amount of indium(III) chloride (10 mol %), 2,2′-dihydroxybiphenyl and bis(2-hydroxyphenyl)methane react quickly, without using any solvent, with ketones or β-keto esters possessing at least one hydrogen atom in α to the ketone-carbonyl group, to afford some new dibenzo(d,f)(1,3)dioxepines and some 12H-dibenzo(d,g)(1,3)dioxocin derivatives, respectively.

氯化铟(III)催化一步合成一些新的二苯并(df)(1,3)二氧杂环庚烷和12 H-二苯并(dg)(1,3)二氧杂环丁烷衍生物

在催化量的氯化铟(III)(10 mol%)的存在下,2,2'-二羟基联苯和双(2-羟基苯基)甲烷在不使用任何溶剂的情况下迅速与酮或至少具有至少3,3-二氨基苯甲酸酯的反应在酮羰基的α中有一个氢原子,分别得到一些新的二苯并(df)(1,3)二氧杂环庚烷和12个H-二苯并(dg)(1,3)二氧杂环丁烷衍生物。
