Abstract
4-(3-Cyano-4-nitrophenyl)phenols are prepared by reacting a 2-cyano-1-nitrobenzene having a replaceable hydrogen in the 4-position with a phenol having a replaceable hydrogen in the 4-position in an inert solvent and in the presence of a strong base. The 2-cyano-1-nitrobenzene and phenol may be substituted or unsubstituted, and preferred phenols include phenol and 2,6-dialkylphenols.
