Abstract

The behavior of tetra(1,2,5-selenodiazolo)porphyrazine in DMSO and in the DMSO-base (pyridine, 2-methyl-pyridine, morpholine, and piperidine) systems has been studied. It has been shown that the π-chromophore system of the macrocycle is decomposed with time in strongly basic media. The proton-transfer complex H2PA(SeN2)4·2DMSO formed in DMSO has been less kinetically stable in the presence of morpholine (piperidine) than the H2PA(SN2)4·2DMSO complex.
