Abstract

Two N -heterocyclic carbene (NHC) palladium complexes of formula [PdBr2 (NHC)(pyridine)] in which the carbenic ring is anked by sterically crowded cavitand substituents were prepared from appropriate imidazolium salts bearing either two resorcinarene or a combination of resorcinarene and calixarene fragments. Both complexes displayed high stability and good activities in the cross-coupling of aryl bromides with phenyl boronic acid. One of the imidazolium salts was characterised by an X-ray diffraction study.
