Aromatic carboxylic acids are found to undergo reactions with isocyanates, wherein triflic acid promotes the formation of aromatic imide products in fair to good yields. It is proposed that the carboxylic acid group directs the isocyanate electrophile to the <i>ortho</i>-position. This is thought to occur by the formation of a temporary carbamic acid anhydride group, which cleaves upon <i>ortho</i>-functionalization. A series of imide products are synthesized, and the synthesis of a potential se ...[more]
