SPIRO-1,1'-BIINDANE-7,7-BISPHOSPHINE OXIDES AS HIGHLY ACTIVE SUPPORTING LIGANDS FOR PALLADIUM-CATALYZED ASYMMETRIC HECK REACTION

摘要

The present invention relates to catalyst complexes comprising palladium (Pd) and at least one spiro-1,1′-biindane-7,7′-bisphosphine oxide ligand as disclosed herein, and their use. The present invention is further directed to the asymmetric catalyzed covalent carbon-carbon single bond formation from aryl, heteroaryl and alkenyl triflates and halides and olefins utilising the said catalyst complexes.
