【 摘 要 】

Weakly coordinating anions show little affinity for binding to unfunctionalized iron(�?) porphyrins. The electron-deficient 5, 10, 15, 20-tetrakis(pentafluorophenyl)porphinatoiron(�?) compound is utilized in this study to demonstrate solution coordination by chloride, bromide and acetate ions. The binding strength of anions to the iron(�?) porphyrin is reflected by a systematic change in pyrrole proton chemical shift in ¹H NMR spectra; the pyrrole resonance moves downfield when the �?-donor ability of anions is decreased.
