摘要：

In the presence of catalytic amount of indium(III) chloride (10mol%), 2,2'-dihydroxybiphenyl and bis(2-hydroxyphenyl)methane react quickly, without using any solvent, with ketones or beta-keto esters possessing at least one hydrogen atom in alpha 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.
