Direct one-pot reductive imination of nitroarenes using aldehydes and carbon monoxide by titania supported gold nanoparticles at room temperature

The direct one-pot reductive imination of nitroarenes with various aldehydes by a titania supported gold catalyst at room temperature using CO/H2O as a reducing agent is illustrated. This method is simple, economic, general and environmentally benign, thus resulting in practical advantages for the synthesis of imines and their derivatives.
