The pyrolysis of N,N'-diacyl-1,2-benzenediamines leads to the formation of 2-substituted benzimidazoles. This new synthetic approach towards the synthesis of 2-substituted benzimidazoles is developed based on the electron impact studies of N,N'-diacyl-1,2-benzenediamines under 70 eV conditions, in which important fragment ions corresponding to 2-substituted benzimidazoles are observed. The mechanisms and ion-structures, proposed in the mass spectral study, are supported by high-resolution, B/E and B2/E linked-scan spectra and Collision Activated Decomposition (CAD)-B/E linked-scan spectra.
α-oxonitrile as a potential acylating agent

The synthetic potential of α-oxonitrile used as N-acylating agent under almost neutral conditions has been explored. Unreported five N,N''-dibenzoyl derivatives 4a-d, g and two N-benzoyl derivatives 3a-c from 4,5-dimethyl-1,2- phenylenediamine 2 and 1,2-phenylenediamine 2 have been synthesized. Their spectral data as well as antibacterial screening of N,N'-4,5-dimethyl-1,2- phenylenediamines are reported.
