✦ Synopsis

Double lithiation of bis(tetra-hydroindenyl)iron followed by phosphorylation using PhzPCl affords two different chiral diphosphines having respectively Ct-and Ca-symmetry. Following antipode separation, the compounds can be used as ligands in Rh-catalyzed hydrogenation (up to 97% ee) and hydroboration (up to 84% ee) of olefins and in Ir-catalyzed hydrogenation ofimines (up to 79% ee).

Cyclodiop, a chiral diphosphine with an intact P-P bond was prepared and used as a ligand in rhodium complexes. Asymnetric reduction of some prochiral olefins was observed. The nature of the rhodium complexes is discussed in the light of their P nmr spectra. The spectacular progress of homogeneous

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
