Bis(isonitrile) iron(II) complexes bearing a C2‐symmetric diamino (NH)2P2 macrocyclic ligand efficiently catalyze the hydrogenation of polar bonds of a broad scope of substrates (ketones, enones, and imines) in high yield (up to 99.5 %), excellent enantioselectivity (up to 99 % ee), and with low catalyst loading (generally 0.1 mol %). The catalyst can be easily tuned by modifying the substituents of
带有C 2对称的二氨基(NH)2 P 2大环配体的双(异腈)铁(II)络合物可以高产率(上)高效催化广泛范围内底物(酮,烯酮和亚胺)的极性键氢化。至99.5%(99.5%ee),优异的对映选择性(高达99%ee),并且催化剂负载量低(通常为0.1 mol%)。通过修饰异腈配体的取代基可以容易地调节催化剂。
