✦ Synopsis

The development of new ligands for asymmetric catalysis is an highly active field of research. [1] Although many chiral ligands have been prepared, only a few, such as binaphthyl-, [2] salen-, [3] pybox-, [4] and DuPHOS-type [5] ligands have found broad applications in various asymmetric reactions. The ferrocenyl unit has proven to allow excellent spatial recognition, [6] and we recently reported new ferrocenyl diphosphanes of type 1 (taniaphos), [7] which gave excellent results in
