Deposition of other organogold complexes

The isonitrile gold(I) nitrate ([AuI(N03)(CN-But)]) has been used to prepare Au/Fe203 89 the complex was added to a slurry of freshly precipitated ferric hydroxide in acetone. After removal of solvent and calcination (673 K), small gold particles ( 4nm) were obtained with a loading of 3wt.% Au. 

The great advantage of using Me2Au(acac) is that it contains no chloride and that it is commercially available (but expensive). Any support can be used, but the preparation must be conducted in the absence of moisture and air. Catalysts made in this way must therefore necessarily remain laboratory curiosities, as the method is quite unsuited to manufacture on a large scale.
