Palladium nanoparticles supported on cucurbit [6]uril: An efficient heterogeneous catalyst for the Suzuki reaction under mild conditions

Article abstract of DOI:10.1002/aoc.3245

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 C-C 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.
