Synthesis of a Tetradentate Pyridyl/Quinoline Ligand and its Iron(II) Complex
High-spin oxoiron(IV) complexes are often postulated as intermediates in the catalytic cycle of nonheme iron oxygenases. Their C−H bond cleaving ability is attributed to the highly reactive quintet (S = 2) spin state. However, as of today, there are very few synthetic complexes that enforce the high spin state and even fewer that retain a high reactivity. In this study, a new tripodal tetradentat
