SYNTHESIS OF MONO(PYRIDINE)- AND MONO(4-SUBSTITUTED PYRIDINE) OCTAETHYLPORPHYRINATOIRON(III) PERCHLORATE

Abstract
Mono(pyridine)- and mono(4-substituted pyridine)octaethylporphyrinatoiron(III) perchlorate were prepared by treatment of octaethylporphyrinatoiron(III) chloride with silver perchlorate and successive addition of pyridine and 4-substituted pyridine, respectively. The spin states of monoamine adducts were found to be in equilibrium between high (S = 5/2) and low (S = 1/2) spin states.
