<p>Stereo isomer-enriched phosphorous compound (I), is new. Stereo isomer-enriched phosphorous compound of formula (I), is new. Either R 1>, R 2>1-30C monovalent residue; or PR 1>R 2>5-9 membered heterocyclic ring containing 2-50C and up to 3 heteroatoms of O or N; n, m : 0-4; R 3>, R 4>F, Cl, Br, I, NO 2, optionally protected formyl, 1-12C-(halo)alkyl, 1-12C-(halo)alkoxy, 5-14C aryl, 6-15C-arylalkyl or residue (II) of formula A 1>-B 1>-C 1>-D 1>; A 1>1-12C alkylene or 2-12C-alkenylene; B 1>O, S or NR 5>; R 5>H, 1-8C alkyl, 6-15C arylalkyl or 5-14C aryl; C 1>carbonyl; D 1>R 6>, OR 6>, NHR 7>or N(R 7>) 2; R 6>1-8C alkyl, 6-15C arylalkyl or 5-14C aryl; either R 7>1-8C alkyl, 6-14C arylalkyl or 5-14C aryl; or N(R 7>) 2= 5-6-membered cyclic amino or residues of formulae A 1>-D 1>, A 1>-SO 2-D 1>, A 1>-NR 6>-SO 2R 6>, A 1>-SO 3Z 1>, A1-PO 3Z 1>2, A 1>-COZ 1>and A 1>-CN; Z 1>H or an equivalent-metal ion; Ar : aryl; and asterisk : place for possible stereo isomeric enriched compounds. Independent claims are included for: (1) the preparation of (I); (2) preparation of stereo isomer-enriched chiral compounds in the presence of (I); transition metal complexes (IX) comprising (I); and (3) a catalyst containing the transition metal complex.
