N-Aryl amides with peri-CH are capable to condense with formaldehyde to yield N-hydroxymethylated N-aryl amides. The enhanced nucleophilicity is attributed to the single conjugation of the amide nitrogen with the acyl group but not the aryl group. Infrared measurements provide additional evidence for the enhanced nucleophilicity of the amides with peri-CH.
