3. We have described how acyl chloride compounds (RC=OCI) can, with the assistance of a Lewis acid catalyst, act as electrophiles in electrophilic aromatic substitution reactions. Like Lewis acids, protonic acids also can enhance the electrophilicity of carbonyl carbons. One equivalent of acetone will react with two equivalents of phenol to form the now notorious compound bisphenol A. The net reaction is indicated here. CHO OH H2SO4 OH HO НАС CH CH, bisphenol A phenol acetone (Note that 2 equivalents...
