Abstract
1,2,4,5‐Tetracyanobenzene reacts under mild conditions with anionic reagents not to polymer but to low molecular weight, high substituted phthalocyanines: 2,3,9,10,16,17,23,24‐octacyanophthalocyanine (3a) and tetrakis(1‐imino‐3‐propoxyisoindolo)porphyrazine (3b). 3a is saponified to the octacarboxyphthalocyanine 3c and converted with hydrazine to tetrakis(1,4‐diaminophthalazino)porphyrazine (3d). Low molecular metal chelates are synthesized starting from 3a and 3c. IR‐ and UV/VIS‐spectra are discussed.
