## Abstract A series of diphosphines of the novel Walphos ligand family all based on a phenylferrocenylethyl backbone were synthesised in a four‐step sequence. In the rhodium‐ or ruthenium‐catalysed asymmetric hydrogenation of olefins and ketones enantioselectivities of up to 95% and 97%, respectiv
