The relative s-donor/p-acceptor qualities of various NHC ligands were examd. and classified in monosubstituted NHC-Rh and NHC-Ir dicarbonyl complexes by IR spectroscopy. For the 1st time, bis(carbene)-substituted Ir complexes were used as catalysts in the synthesis of arylboronic acids starting from pinacolborane and arene derivs. .
