PHOSPHORUS SULFUR AND SILICON AND THE RELATED ELEMENTS
New chiral diphosphines 2,2 "-bis[1-(disubstituted phosphino)ethyl]-1,1 "-b
iferrocene, having both central and planar elements of chirality, was desig
ned for a trans-chelating chiral diphosphine ligand (TRAP) for transition m
etals and synthesized form optically active N,N-dimethyl-1-ferrocenyl ethyl
amine. Some transition-metal complexes with the TRAP ligands were prepared
and utilized as a chiral catalyst for asymmetric synthetic reactions.
