Impregnation of Other Organogold Complexes

Isonitrile gold(I) nitrate, AuCNBu NOs, was used as a precursor for the impregnation of Fe203 in acetone (3 wt% Au) [81]. TUler calcination at 400°C, gold particles probably smaller than 4 nm were obtained. 

Gates group has extensively used Au(CH3)2(acac) for the preparation of gold catalysts by impregnation of various supports in dried pentane or hexane MgO 

The obvious advantage of using organometallic gold precursors is that they do not contain chloride, and that any oxide support can be used. However, gold acetylacetonate is expensive, and the preparations must be performed in the absence of moisture and air.
