✦ Synopsis

The new metal-free phthalocyanine 2 and phthalocyaninatometals 3-5 (M = Ni, Co and Zn) carrying eight hydroxyethylmercapto groups on peripheral positions have been synthesized from 1,2-bis(hydroxyethylmercapto)-4,5-dicyanobenzene in the presence of a suitable anhydrous metal salt [NiCl 2 , CoCl 2 or Zn(O 2 CMe) 2 ] or hydroquinone. Zinc (II) phthalocyaninate reacted with palladium(II) salt to form complexes with a phthalocyanine (metal ratio of 1:4). The electrical conductivity of the phthalocyanines 2, 3, 5, 5a are in the semiconductor range.
