Abstract New phenylthio-substituted phthalodinitriles have been synthesized: 5-amino-4- phenylthio-, 5-acetylamino-4-phenylthio-, 5-octanoylamino-4-phenylthio-, 5-phenoxy-4- phenylthio-, 5-(4-carboxyphenoxy)-4-phenylthio-, 5-(4-tert-butylphenoxy)-4-phenylthio-, and 4, 5-bis (phenylthio) phthalodinitriles. Their complexes with metals have been prepared and examined by spectral methods.
