Selective oxidation of sulfides to sulfoxides is an essential step of many biological and
industrial processes, leading to sulfoxides, playing the role of essential intermediates
since then, a number of methods have been developed for conversion of sulfides into
sulfoxides [1, 2]. Reaction of Fe(acac)3 and 2-(2'-hydroxyphenyl)oxazoline (Hphox) as a
bidentate O, N donor ligand afford a six-coordinated iron(III) complex [Fe(phox)2(acac)]
with the distorted octahedral configuration. Complex, [Fe(phox)2(acac)] was isolated as
an air-stable crystalline solid and fully characterized by elemental analysis, FT-IR,
solution electrical conductivity, and finally by single-crystal X-ray structure analysis.
Oxidation of sulfides to their corresponding sulfoxides was conducted by this catalyst
using urea hydrogen peroxide (UHP) as an oxidant at room temperature under air. The
catalyst shows very efficient reactivity in the oxidation reactions giving high yields and
selectivities. Easy preparation, mild reaction conditions, high yields of the products, short
reaction time and high selectivity make this catalytic system a useful method for
oxidation reactions.
