| Abstract: | Acid-base interactions of benzoannelated trifluoromethylphenylporphyrazines in a CH2Cl2-CF3COOH medium were studied. The stability constants of the acid forms were determined and assumptions were made concerning their structure. It was shown that successive introduction of benzene rings into a porphyrazine molecule enhances the macrocycle basicity. |
