Reactivity of two isomeric quinone dimers, 5,5'-di-tert-butyl-2,2'-bisbenzoquinone (2) and 6,6'-di-tert-butyl-2,2'-bisbenzoquinone (3) have been compared. Both quinone dimers underwent thermal cyclization in ethanol to give dibenzofuran-1,4-diones exclusi

The oxidative coupling of twelve 2-halophenols (1a-1l) was carried out with K3Fe(CN)6 in benzene solution to obtain the corresponding dibenzofuran derivatives.However, only a small amount of the desired dibenzofurans such as 2,6-di-tert-butyl-8-methoxybenzofuran-1,4-quinone (9) and 4,8-di-tert-butyl-2,6-di-isopropyl-1-hydroxydibenzofuran (11) were obtained from 2-bromo-6-tert-butyl-4-methoxy- (1d) and 2-bromo-4-tert-butyl-6-isopropylphenol (1g), respectively.In the other cases, alternative type of products or tarry materials were formed.
