The acylation of 2-aminoacyl-4-chloroanilines with acid anhydrides has given N,N′-diacyl derivatives of 4-chloro-1,2-phenylenediamine. Their fungicidal activities have been investigated. It has been shown that in cotton plants they are converted into 2-alkyl-5-chlorobenzimidazoles.

N,N′-diacyl derivatives of 4-chloro-1,2-phenylenediamine show fungicidal activity against cotton root rot, with potential as a new cotton pesticide.
