Synthesis and properties of bromine-substituted Co(II) tetraphenylporphyrinates

Аннотация

The interaction of bromine-substituted tetraphenylporphyrins with cobalt(II) acetate in a chloroform–methanol mixture yielding the corresponding cobalt(II) porphyrinates has been studied by means of spectrophotometry. Treatment of Co(II) porphyrinates with bromine in the same medium has afforded the Co(III) porphyrinates.
