Iron(III) Schiff base chelates [Fe<SUB>2</SUB>(PA<SUB>2</SUB>ppd)<SUB>2</SUB>Cl<SUB>4</SUB>]Cl<SUB>2</SUB> (<B>1</B>), [Fe<SUB>2</SUB>(PA<SUB>2</SUB>mpd)<SUB>2</SUB>Cl<SUB>4</SUB>]Cl<SUB>2</SUB> (<B>2</B>), and [Fe(PA<SUB>2</SUB>opd)Cl<SUB>2</SUB>]Cl (<B>3</B>), were synthesized, where (PA<SUB>2</SUB>ppd), (PA<SUB>2</SUB>mpd), and (PA<SUB>2</SUB>opd) are the Schiff bases derived from 2-pyridinecarbaldehyde (PA), and <I>p</I>-phenylenediamine (ppd), <I>m</I>-phenylenediamine (mpd), and <I>o</I>-phenylenediamine (opd) respectively. The complexes <B>1</B>, <B>2</B>, and <B>3</B> catalyzed the epoxidation of alkenes with iodosylbenzene as an oxidant providing a chemical model for cytochrome P-450. The binuclear complexes (<B>1</B>, <B>2</B>) were superior to the mononuclear complex (<B>3</B>) as the catalyst for epoxidation of norbornene. Addition of pyridine bases increased the rates, and yields of epoxidation.
