Optically active diphosphine (S,S)-2,2"-bis[(diethylphosphino)methyl]-1,1"-biferrocene (abbreviated to (S,S)-EtTRAP-H) was synthesized from ferrocenyloxazoline derived from L-valinol in 47% overall yield. The new chiral ligand, (S,S)-EtTRAP-H, which coordinates to a rhodium atom in a trans-ehelating
