  脂肪酶催化的醇和胺类拆分仅产生所需对映体纯产品的50％。但是，添加消旋化催化剂会导致100％的动态动力学拆分（DKR）收率。需要快速且与酶促反应条件相容的新型外消旋化催化剂。我们表明，阳离子半三明治钌和iridacycle络合物在手性醇和胺的外消旋中具有很高的活性和效率。在用碱活化后，这些络合物能够选择性消旋醇，而未活化的络合物则是胺消旋的选择性催化剂。我们已将消旋环应用于外消旋β-氯醇的DKR中，以在双相系统中以高收率和高ee产生手性环氧化物（ee =对映体过量）。

  (HT) fashion, stoichiometric amounts of α‐halo carbonyl compounds have been employed as hydrogen acceptors. The reason that these substrates lead to quasi‐quantitative conversions has been tacitly attributed to both thermodynamic and kinetic effects. To provide a clear rationale for this behavior, we investigate herein the redox equilibrium of a selected series of ketones and 2‐propanol by undertaking

  为确保醇氧化的准不可逆性以及氢转移（HT）方式使酮还原，已使用化学计量的α-卤代羰基化合物作为氢受体。这些底物导致准定量转化的原因被默认归因于热力学和动力学效应。为了提供这种行为的明确理由，我们在这里通过结合实验和理论方法的研究来研究所选系列的酮和2-丙醇的氧化还原平衡。首先，研究了短乳杆菌（LBADH）的（R）特异性醇脱氢酶在这些底物上的活性。苯乙酮/（R的对接酶活性位点中的）-1-苯乙醇和α-氯苯乙酮/（S）-2-氯-1-苯乙醇证实似乎没有结构上的卤代醇缺乏反应性的原因。相应的铝催化Meerwein-Ponndorf-Verley-Oppenauer（MPVO）反应提供的转化率与LBADH得到的转化率相似，从而证实了这一假设，表明所观察到的反应性与所用催化剂无关。虽然酶促还原反应的初始速率和IRν（CO）值与普遍认为吸电子基团增加了羰基的亲电性的普遍看法相反，但计算得出的ΔG这些系列
