Cyclotrimerization of 4,5-bis(hexylthio)phthalodinitrile (1) in 1-chloronaphthalene in the presence of BCl3 leads to the subphthalocyanine 4. Unsymmetrical phthalocyanines (5, 6) with six alkylthio substituents on three of the benzenoid units are synthesized by the reaction of 4 with an diminoisoindoline derivative (R' = H or NO2). These extremely soluble compounds are characterized by IR, H-1- and C-13-NMR as well as UV/Vis spectra.
