Chiral ferrocenyl tridentate phosphine ligands were synthesized and used in asymmetric hydroamination reactionscatalyzed by Ni(II)-complexes. Compounds of the type [Ni(PPP)L]2+, where L is a chloride, solvent molecule or a coordinated substrate, were isolated. The efficiency of these complexes in asymmetric catalysis was high when aliphatic or aromatic amines were reacted with electron-poor olefins

Ni(II) complexes containing chiral tridentate ferrocenyl phosphines (Ni(PPP)) have been found to efficiently catalyse the hydroamination of activated olefins with both anilines and aliphatic amines at r.t. (TON up to 71, TOF up to ca. 3 h−1, and enantioselectivities up to 69% ee).
