Description

Complexes of dysprosium(3), europium(3) and neodymium(3) with tetraazaporphin have been synthesized for the first time from tetraazaporphnic ligand and the relevant metal acetylacetonate. Kinetic stability of the complexes in acetic acid solutions in water and methanol is studied. It is shown that in the media mentioned the complexes are subjected to solvoprotolytic dissociation with formation of tetraazaporphin ligand. Kinetic parameters of solvoprotolytic dissociation are ascertained and reaction mechanism is suggested. Kinetic stability succession of the complexes studied is determined

Abstract (Russian)

Впервые синтезированы комплексы диспрозия(3), европия(3) и неодима(3) с тетаазопорфином из лиганда тетраазапорфина и соответствующего ацетилацетоната металла. Исследована кинетическая устойчивость комплексов в растворах уксусной кислоты в воде и в метаноле. Показано, что в этих средах комплексы подвергаются сольвопротолитической диссоциации с образованием лиганда тетраазопорфина. Определены кинетические параметры сольвопротолитической диссоциации и предложен механизм реакции. Установлен ряд кинетической устойчивости исследуемых комплексов
