The macrocyclization reactions led to higher-symmetry and lower-symmetry porphyrazines bearing peripheral 2,5-di(4′-chlorophenyl)pyrrol-1-yl and dimethylamino substituents, which were characterized using NMR and X-ray crystallography. The reactions were performed in the conditions of Linstead macrocyclization with magnesium n-butanolate in n-butanol with an addition of a malonitrile derivative in...
The synthesis and characterization of porphyrazines possessing 2,5-diphenylpyrrol-1-yl and dimethylamino peripheral groups and their precursors are shown. Bulky pyrrolyl substituents influenced the physicochemical properties and solid-state structure of novel porphyrazines and did not hamper the formation of the porphyrazine associates in solution and solid-state. Occurrence of centrosymmetric dimers...
