Aryl iodides as strong inhibitors in gold and gold-based bimetallic quasi-homogeneous catalysis.

ABSTRACT

The strong inhibitor effect of aryl iodides on the quasi-homogenous gold-catalyzed oxidation reaction was described. Aryl iodides were adsorbed on the exposed surface of Au clusters, which affected the accessibility of the nanoclusters to the reacting species and acted as strong inhibitors in catalysis.
