M. Hanack et al., SYNTHESIS OF SOLUBLE OCTASUBSTITUTED PHTHALOCYANINATOPLATINUM AND PHTHALOCYANINATOPALLADIUM COMPLEXES, Synthesis, (4), 1993, pp. 387-390
The octasubstituted phthalocyaninatoplatinum and -palladium compounds
7a-d soluble in common organic solvents were synthesized from the corr
esponding substituted 1,2-dicyanobenzenes 5a-c via the 1,3-diimino-1,3
-dihydroisoindoles 6a-c according to pathways A, B, and C.
