Stability of Palladium(II)‎ beta-cyclodextrin nanocomposite in aqueous media and its catalytic activity in homocoupling of arylboronic acid

الملخص EN

Palladium(II) beta-Cyclodextrin (Pd(II)-β-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)-β-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)-β-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)-β-CD nanocomposite stock solution in water for homocoupling reaction of ArBA decreases with time significantly.

The Stability of the Pd(II)-β-CD nanocomposite was monitored using Ultra Violet- Visible (UV-Vis) spectroscopy.
