The synthesis of 1,4,5,8,9,12-hexaazatriphenylene (HAT), a new ligand for low-valent transition metals, is described; it gives mono-, bis- and tris-chromium tetracarbonyl complexes.The CO stretching frequencies in (HAT)Cr(CO)4 show that HAT is a stronger electron acceptor than 1,10-phenanthroline.
2,3-DIPHENYL- AND 2,3,6,7-TETRAPHENYL-HEXA-AZATRIPHENYLENE, LIGANDS FOR TRANSITION METALS

2,3-Diphenyl-1,4,5,8,9,12-hexa-azatriphenylene 2 and 2,3,6,7-tetraphenyl-1,4,5,8,9,12-hexa-azatriphenylene 3 can be synthesized by the direct condensation of hexa-aminobenzene with glyoxal and benzil.It is, however, not possible to make specifically one of the compounds, which is always accompanied by the parent compound 1 and the fully substituted hexaphenyl-hexaazatriphenylene 4.It is nevertheless possible to optimize the yields of 2 and 3 by a careful choice of the experimental conditions.
