✦ Synopsis

E Ar-type reactions of various heterocycles with ortho-substituted (1%S,P)-tricarbonyl[(1-chloroethyl)-h 6 -benzene]chromium(0) derivatives lead to a family of novel planar chiral bidentate and pseudo-bidentate ligands. Two members of this family (1%S,P)-2-[1%-tricarbonyl-h 6 -((2¦-P,P-diphenylphosphino)phenyl)-chromium(0))ethyl] furan and thiophene show high activity and enantioselectivity in the Pd-catalyzed hydrosilylation of styrenes.
