The oxidation of water (H2O) to dioxygen (O2) is important in natural photosynthesis. One of nature’s strategies for managing such multi-electron transfer reactions is to employ redox-active metal–organic cofactor arrays. One prototype example is the copper tyrosinate active site found in galactose oxidase. In this work, we have implemented such a strategy to develop a bio-inspired nickel phenolate
水(H 2 O)氧化为双氧(O 2)在自然光合作用中很重要。处理这种多电子转移反应的自然策略之一是采用氧化还原活性金属-有机辅因子阵列。一个原型的例子是在半乳糖氧化酶中发现的酪氨酸铜活性位点。在这项工作中,我们已经实施了这样一种策略,以开发一种生物启发性的酚镍镍络合物,该络合物能够在中性pH下以适度的超电势催化H 2 O氧化为O 2。事实证明,使用氧化还原活性配体是避免形成高价镍中间体的有效策略,同时保留了合理的周转率(0.15 s –1)。
