| Research Abstract |
Bimetallic nanocluster catalysts derived from gold and iron group metals were developed, and they could be applied to oxidative amide formation from an alcohol and an amine using molecular oxygen as oxidant. On the other hand, alloyed nanoclusters prepared from gold and palladium gave imine selectively from the same starting materials. Au nanoclusters with size of 5 to 10 nm showed excellent activity for oxidative amide formation from aldehydes and amines. Furthermore, a cooperative catalytic system of gold-palladium alloyed nanoclusters and Lewis acids facilitates alkylation of primary amides to secondary amides through hydrogen autotransfer mechanism from primary amides and alcohols.
