Oxygenation of a new bis-fenced porphyrinato iron without amide groups: 5,10,15,20-tetrakis(2,6-bispivaloyloxyphenyl)porphyrinatoiron(II)
Abstract
A new porphyrinatoiron complex, 5,10,15,20-tetrakis(2,6-bispivaloyloxyphenyl)porphyrinatoriron(II), has been synthesized; axial-base ligation was sterically depressed by the four ester groups on each side of the porphyrin plane and a stable dioxygen adduct formed reversibly at 25 °C in toluene.
