Abstract: | Bromination of tetra(tert-butyl)porphyrazine by N-bromosuccinimide in chloroform results in the formation of mono- and dibromides, substitution for the bromine atoms of which produced the corresponding cyano, phenoxy, phenylthio, styryl, phenylethynyl and piperidino derivatives. From the monobromide and 2,2-bis(p-hydroxyphenyl)propane, the dimeric porphyrazine 2,2-bis[p-tetra(tert-butyl)porphyrazyloxyphenyl]propane was similarly obtained.Scientific Research Institute of Organic Intermediate Products and Dyes, Moscow 103787.
