Synthesis and characterization of novel metal free and metallo- phthalocyanines containing substituted benzothiazol moieties in microwave irradiation media

In this work, A new type soluble phthalocyanine and its complexes not recording in literature were synthesized. 4-(1,3-benzothiazol-2-yl)phenol (3) was prepared by the reaction of 2-aminobenzenethiol (1) with 4-hydroxybenzaldehyde (2). 4-[4-(1,3-benzothiazol-2-yl)phenoxy]phthalonitrile (5) was prepared by the reaction of 4-(1,3-benzothiazol-2-yl)phenol (3) with 4-nitrophthalonitrile (4). The metal free phthalocyanine was synthesized from compound (5) in dimethylaminoethanol. Metallophthalocyanines (7), (8), (9), (10) were sythesized by the reaction of compound (5) in dimethylaminoethanol with Ni, Pb, Zn, Cu salts, respectively. The structures of the synthesized compounds were identified by using IR, 13C-NMR, 1H-NMR, and MS spectrometers.
