FUNCTIONALIZED N-HETEROCYCLIC CARBENE OF PALLADIUM (II) AS EFFICIENT HETEROGENEOUS CATALYST IN WATER

摘要

N-Heterocyclic carbenes (NHCs) are known to form exceptionally stable complexes with many metals. Consequently, they have emerged as versatile donor ligands in transition-metal catalysis and several highly selective applications in asymmetric catalysis have been reported. Nanoparticles can be considered a semi-heterogeneous support as they are readily dispersed in the reaction medium, exhibit an intrinsically high surface area, and display highly accessible surface-bound catalytic sites. Nanoparticles offer also an easy work-up procedure and a higher recyclability of the catalyst.
