First planar chiral bidentate ligand based on a (eta5-cyclopentadienyl)(eta4-cyclobutadiene) cobalt backbone: high efficiency in enantioselective palladium-catalyzed allylic substitutions.
The synthesis of the planar chiral (R)-[eta5-(1-diphenylphosphino-2-tert-butylsulfenyl)cyclopentadienyl](eta4-tetraphenylcyclobutadiene) cobalt and its high efficiency as P,S-bidentate ligand in Pd-catalyzed allylic substitutions is described.
