Phosphorylatedsulfonimidamides (SIAPhos) undergo ion exchange reactions with cationic complexes, [Rh(cod)2BF4] and [Ir(cod)2BarF], or neutral complexes [Rh(cod)Cl]2 and [Ir(cod)Cl]2, leading to unprecedented neutral complexes with P‐N‐S‐N chelates. Use of the resulting neutral iridium complexes in asymmetrichydrogenation reactions of tri‐ and tetrasubstituted enamides leads to products with high
