Abstract

The preparation of several bis(1,4-diazepinium) salts from the reaction of three 1,2-diamines with a bis(vinamidinium) salt is described. Bis(?-substituted pentamethine cyanine(dyes are also prepared from the reaction of vinamidinium salt with 1,2-dimethylquinolinium perchlorate and 1,2,3,3-tetramethyl-3Hindolium perchlorate. Data from elemental analyzes, IR, 1H-NMR, 13C-NMR, and mass spectra (MS) confirm the molecular structure of the obtained products.
