Simple commercially available TiO2 in ionic liquids (ILs) promotes the oxidative catalytic coupling of anilines to diazo compounds. For example, the reaction of aniline with molecular oxygen (5 bars) in the presence of TiO2 and functionalised imidazolium-based ILs affords azoxybenzene in up to 85% selectivity. The catalytic selectivity and activity are mainly related to the viscosity, oxygen solubility, and stability of the superoxide ion (O2-) and ionic species provided by the IL (IL effect). This effect is evident since most of the reactions performed in the presence of ILs gave as major products the azoxybenzene zwitterions. This is in opposition to that performed in toluene, which gave almost exclusively azobenzene.
