Mercury catalyzed hydration mechanism
Webhydration catalyzed by CuCl. As Fig. 3 shows, to figure out the role of the S-containing organic compounds in the process, we proposed a possible hydration mechanism based on the alkyne dimerization and hydration mechanisms [4, 21, 26–31]. First, the S-contain-ing compound coordinates with the Cu(I) complex to give complex I.

Abstract: Curcumin, known as a potential antioxidant and anti-inflammatory agent, has major limitations for its therapeutic use because of its lack of water solubility and relatively low bioavailability. We report for the first time the loading of different metal oxide aerogels with curcumin.
