脱氢/加氢催化反应的可逆性一直是均相催化的一个难以实现的目标。本文报道了仲醇和二醇在铁钳形络合物上的可逆无受体脱氢反应，以及仲醇的可逆氧化脱氢反应和醛的还原反应，其中质子和电子的转移是分开的。这种反应性表明了一种开发用于含羟基燃料部分氧化(脱氢)的可逆燃料电池电催化剂的策略。
Reversibility of a dehydrogenation/hydrogenation catalytic reaction has been an elusive target for homogeneous catalysis. In this report, reversible acceptorless dehydrogenation of secondary alcohols and diols on iron pincer complexes and reversible oxidative dehydrogenation of primary alcohols/reduction of aldehydes with separate transfer of protons and electrons on iridium complexes are shown. This reactivity suggests a strategy for the development of reversible fuel cell electrocatalysts for partial oxidation (dehydrogenation) of hydroxyl-containing fuels.
