    • The occurrence of the deoxygenation at gold NPs on Au/HT was confirmed as follows: Au/HT was removed from the reaction mixture at 50% conversion of 1a. Continued stirring of the filtrate under similar conditions did not give any further products. In addition, no gold ions in the filtrate were confirmed by inductively coupled plasma (ICP) analysis.
