Abstract:

The catalysis reactions by gold compounds has appeared as a powerful tool in synthesis. Research on catalysis with gold content has rapidly become a hot topic in chemistry. Gold is shows equally effective as both heterogeneous and homogeneous catalysts. In this review，we attempt to incorporate these two facts to demonstrate this new found and general efficacy of gold in reactions，especially in some important industrial chemical processes. The latest discoveries are placed within a historical context，but the main focus is to highlight the new catalytic possibilities that gold-catalyzed reactions currently offer synthetic chemist，in particular in CO oxidation，water gas shift reaction，hydrogenation，carbonylation，CH bond activation，H₂O₂ synthesis reaction and nucleophilic additions etc. Some aspects of reaction mechanism and applied engineering of these multiphase catalytic reactions have also been reviewed，with about 49 latest references.
