Abstract: Chiral di-phosphonites and phosphhours diamides based on the ps-ortho disubstituted p-cyclophane skeleton are good ligands for transition metals, notably rhodium, iridium and ruthenium. Preferably, the transition metals are linked to the ligands by a diene compound chosen from 2,5-Norbornadiene (NBD) and 1,5-Cyclooctadiene (COD).
