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