Oxidation of 4(2-hydroxyphenoxy)anilines 1b to 1d with active manganese dioxide leads directly to quinone mono-ketals 2b to 2d in reasonable yield. Similar reaction of 4 (2-sulfonamidophenoxy)anilines 9a, 9b provides an efficient synthesis spirobenzoxazolecyclohexadienones 10a and 10b but treatment with manganese dioxide of alcohol 3 and oxime 6 gives respectively azobenzene 4 and terphenyl 7 rather than spirodienones.
