SYNTHESIS OF PHTHALOCYANINES CROSSWISE-SUBSTITUTED WITH 2 ALKYLSULFANYL AND 2 AMINO-GROUPS

Crosswise-substituted phthalocyanines (4, 4a-c) with two nitro and two dodecylsulfanyl groups are synthesized by a 2:2 condensation of ,3-di imino-6-(n-dodecylsulfanyl)isoiminoindolenine (2) with 6-nitro-1,3,3-t richloroisoindolenine (3) in the presence of sodium methoxide, hydroqu inone and triethylamine. Nitro substituents are reduced to amines by s odium sulfide and condensation of the amine groups with ferrocenylalde hyde results in a new pc with two ferrocenylimino substituents, The no vel compounds are characterized by UV/vis, mass and H-1-NMR spectrosco py.
