Unexpected condensation of 4,5-dimethyl-1,2-phenylenediamine with phthalaldehyde to 4,5-dimethyldiisoindolo[2,1-a:1,2-c]quinoxaline-1,8-dione initiated by NiII complexes
Abstract:
The title condensation initiated by Ni9(HOOCCMe3)4(μ4-OH)3(μ3-OH)3(OOCCMe3)12 in toluene or NiCl2·6H2O in ethanol was studied, and the molecular structure of the product was found using X-ray diffraction.
