An unusual involvement of NaIO4 in the acetylation of bisphenol during attempted oxidative acetylation

An unexpected behaviour of compilation of reagent sodium metaperiodate in acetic anhydride for acetylation of bisphenols was observed during attempted oxidative acetylation of bisphenols for the synthesis of a bis-acetoxy cyclohexadienone. The products were characterized by their spectral and analytical data and a probable mechanism for acetylation involving role of NaIO4 is proposed.
