developed hydrogenation of CO2 and hydrogen carbonate catalyzed by half-sandwich complexes with 4,4′-dihydroxy-2,2′-bipyridine (dhbp) and 4,7-dihydroxy-1,10-phenanthroline (dhpt). An unprecedented high catalytic activity and reusability of the catalyst without waste generation were achieved by automatic tuning of the catalytic activity and water solubility of the catalyst through the acid–base equilibrium
本微观评论重点介绍了最近开发的由 4,4'-二羟基-2,2'-联吡啶 (dhbp) 和 4,7-二羟基-1,10-菲咯啉 (dhpt )。通过催化剂配体的酸碱平衡自动调节催化剂的催化活性和水溶性,实现了催化剂前所未有的高催化活性和可重复使用性,且不会产生废物。酚羟基产生的氧阴离子在电子效应和极性中起着重要作用。催化剂设计概念和配体的优异性能有望对新型均相催化剂的设计产生更广泛的影响。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
