IMPROVED METHOD FOR PREPARATION OF 4,5-DICHLOROPHTHALONITRILE AND SYNTHESIS OF 4-CHLORO-5-(R-AMINO)PHTHALONITRILES ON ITS BASIS
Аннотация и ключевые слова
Аннотация (русский):
The paper investigates the influence of the nature of N-nucleophiles on the reaction of activated aromatic nucleophilic substitution of chlorine atom in 4,5-dichlorophthalonitrile. The authors synthesised 4-chloro-5-(R-amino)phthalonitriles not described in the literature. They are promising compounds for the synthesis of phthalocyanines with increased organosolubility.
