ChemInform Abstract: Palladium Nanoparticles Supported on Cucurbit[6]uril: An Efficient Heterogeneous Catalyst for the Suzuki Reaction under Mild Conditions.

Abstract

A new NC palladacycle was synthesized and supported on cucurbit[6]uril (CB[6]). The CB[6]-supported palladium was used as an efficient nanocatalyst for the Suzuki reaction. In these reactions various aryl halides were reacted with arylboronic acids in H2O–EtOH at both room temperature and 40 °C. The obtained Pd nanocatalyst exhibited excellent reactivity and stability in CC bond formation, which confirms that the catalyst is a completely active heterogeneous species. The Pd nanocatalyst was characterized using X-ray diffraction, scanning electron microscopy and transmission electron microscopy. Copyright © 2014 John Wiley & Sons, Ltd.
