Nucleophilic attack by N2 of N1,N2-diarylformamides 1a-c on C-2 of chloranil (2) and subsequently by N1 on C-1 of 2 initiates the formation of benzimidazolinones 8a-c.In contrast, when 1b-e is reacted with 2,3-d
SPECTROPHOTOMETRIC DETERMINATION OF AMINES WITH P-CHLORANIL.

Primary, secondary, and tertiary amines, both aliphatic and aromatic are shown to react with p-chloranil in dioxane/2-propanol (1:4, v/v) to produce a blue to purple color. Most amines tested also react with p-chloranil in other organic solvents. The colored compound formed can be stable for 8 h at room temperature, depending on the amine and the solvent used. Several organic compounds (phenol, epoxies, alkynes, and non-amine nitrogens) are shown to not interfere with the detemination of amines. A few applications of amine determinations in real samples are discussed.
