Abstract

Palladium(II) beta-Cyclodextrin (Pd(II)-b-CD) nanocomposites are water-soluble compounds which can be of great importance for performing palladium-catalyzed reactions in aqueous media. The stability of water-soluble  Pd(II)-b-CD nanocomposites in water were examined and was found that this nanocomposit is losing its stability in water significantly with time in the time interval of 0 to 200 minutes.  In addition, the  Pd(II)-b-CD nanocomposite was used as a catalyst for Aerobic homocoupling of arylboronic acid (ArBA) in water. However, the results showed that the catalytic activity of same prepared Pd(II)-b-CD nanocomposite stock solution in water for homocoupling reaction of ArBA decreases with time significantly. The Stability of the  Pd(II)-b-CD nanocomposite was monitored using Ultra Violet- Visible (UV-Vis) spectroscopy.  used to monitor the catalyst stability
