Abstract
The formation of imines by aerobic oxidative coupling of mixtures of alcohols and amines was
studied using gold nanoparticles supported on titanium dioxide, TiO2, as a heterogeneous
catalyst. The reactions were performed at ambient conditions (room temperature and atmospheric
pressure) and occurred with excellent selectivity (above 98%) at moderate conversion under
optimized conditions. The effect of catalytic amounts of different bases was studied, along with
reaction temperature and time. Utilisation of a selective catalyst system that uses dioxygen as an
oxidant and only produces water as by-product represents a new green reaction protocol for imine
formation.
