PALLADIUM/BENZIMIDAZOLIUM SALT CATALYST SYSTEMS AND N-HETEROCYCLIC CARBENE-PALLADIUM(II)-PYRIDINE (PEPPSI) COMPLEXES FOR ANTI-MARKOVNIKOV HYDROAMINATIONS OF STYRENE IN IONIC LIQUID

Abstract

Both in situ prepared Pd-NHC and NHC-Pd-PEPPSI complexes were tested as catalysts in the intermolecular hydroamination reactions between styrene with various anilines in ionic liquid. All of the compounds tested here are catalytically active for the intermolecular hydroamination of styrene with aromatic amines. The anti-Markovnikov addition products were obtained selectively by using 1 mol% of the palladium complex.
