The oxy-globin models Fe(Por)(NH3)(O2), prepared by sequential reactions of O2 (18O2) and NH3 with thin porous layers of FeII(Por), react with NO (15NO) at 80â100 K to form only the low-spin nitrato complexes Fe(Por)(NH3)(η1-ONO2), thus implying that peroxynitrite intermediates, if formed, must undergo very facile isomerization to the nitrato analog.
通过 O2 (18O2) 和 NH3 与 FeII(Por) 薄多孔层的连续反应制备的氧球蛋白模型 Fe(Por)(NH3)(O2)在 80â100 K 下与 NO (15NO) 反应,只形成低自旋的亚硝基络合物 Fe(Por)(NH3)(δ-1-ONO2),这意味着如果形成过
亚硝酸中间体,必须经过非常容易的异构化才能成为亚硝基类似物。
