ACCEPTED MANUSCRIPT
The development of a sustainable protocol for the oxidation of primary and secondary alcohols, two diols and glycerol catalyzed
by the iron complexes [FeL3](OTf)2 (L = bipy, DMbipy, bpm, phen, DMphen) and [FeL2](OTf)2 (L = bpa, terpy) has been
described here. Although some of the iron precursors employed were already known as competent catalysts for alcohol oxidation,
in the present work the investigations were extended to other similar complexes, and most importantly all reaction conditions
were tuned towards a greener approach. Thus, the catalytic reactions were performed with microwave heating, using hydrogen
peroxide as green oxidation agent and aqueous reaction medium, to which addition of a small amount of organic solvent was
needed to produce highest reaction yields. Interestingly, a beneficial role of some heterocyclic aminoacids as cocatalysts was
observed; the role of such additives in the catalytic reaction was studied by means of NMR and UV-Visible spectroscopies,
providing indications that aminoacid coordination did not take place, but its presence in solution influenced the reactivity of the
iron complex with hydrogen peroxide.
