Condensation of unsymmetrical aromatic diamines (4-methyl-, 4-chloro-, and 4-nitrophenylenediamines) 2-4 with 2-hydroxy-6-methyl-4-pyrone 1 have been examinated. The structure of isomerie 4-acetonylidene-1,5-benzodiazepin-2-ones 5-10 and benzimidazoles 11-16 obtained from competitive reactions have been established by the spectrale data (1H NMR, IR and mass spectrum). The position of the substituents in 6/9 and 7/10 was proved by comparison with samples with authentic structures.
