The acid catalysed dienone-phenol rearrangement of methyl substituted o -propargyl-cyclohexadienones (scheme 3) was investigated. The rearrangements were carried out in acetic anhydride containing about 1 0 / 00 sulfuric acid. Under these conditions acetoxy benzenium ions are formed as intermediates....
