Kinetics of Iridium(III) Catalysed Oxidation of Butane 1:4-Diol with Alkaline Hexacyanoferrate(III)

Abstract

Studies of the kinetics of iridium(III) chloride catalysed oxidation
of butane-1 :4-diol by aqueous alkaline hexacyanoferrate(III)
(HCF) were made at constant ionic strength. The results suggest
the complex formation between iridium(III) species and the substrate
anion. This complex with hexacyanoferrate(III) gives another
complex which slowly decomposes into univalent Ir(I) species and
the intermediate products which in turn are further oxidised by
HCF(III) into the subsequent steps.
