Synthesis and spectral properties of β-bromo-substituted nickel(II) tetraphenylporphyrins

Аннотация

Bromination of (5,10,15,20-tetraphenylporphyrinato)nickel(II) with N-bromosuccinimide in chloroform and chloroform–dimethylformamide mixture and complexation of 2-bromo-5,10,15,20-tetraphenylporphyrin and 2,3,12,13-tetrabromo-5,10,15,20-tetraphenylporphyrin with nickel(II) acetate in dimethylformamide have been studied. The resulting nickel(II) complexes with mono-, tetra-, and octabromo-5,10,15,20-tetraphenylporphyrins have been identified by electronic absorption, IR, ¹H NMR, and mass spectra.
