Notes:
Octa-tert-butylphthalocyanina-tonickel(II) (4) was synthesized from 3,5-di-tert-butylphthalonitrile (1) and nickel acetate. A nonstatistical mixture of the four structural isomers 4a-d was obtained. The isolation of the structural isomers 4a-d by preparative HPLC (MPLC) allowed their unequivocal identification and characterization by spectroscopic techniques. Moreover, a new family of tert-butyl-substituted phthalocya-nines 6-10 containing dienophilic functionalities were prepared by condensation of 3,5-di-tert-butylphthalonitrile (1) with 6,7-dicyano-1,4-epoxy-1,4-dihydronaphthalene (5). The separation of the phthalocyanines 6-10 and of some of their structural isomers was accomplished by normal column chromatography. The structural isomers were characterized by spectroscopic methods in terms of their symmetry.
