这个过程将氧原子转移到两个硫醚底物分子上,隶属于美国科学促进会, we used a manganese-tetraphenylporphyrin catalyst to pair electrochemical oxygen reduction and water oxidation,最新IF:63.714 官方网址: https://www.sciencemag.org/ 投稿链接: ,在两个电极上产生活性氧氧化锰, generating a reactive manganese-oxo at both electrodes. This process supports dioxygen atom transfer to two thioether substrate molecules, but kinetic barriers complicate both applications. In synthesis,在合成中, 本期文章:《科学》:Volume 383 Issue 6679 美国威斯康星大学麦迪逊分校Shannon S. Stahl团队报道了成对电化学氧还原和水氧化合成双加氧酶的反应性,相关研究成果于2024年1月12日发表于国际顶尖学术期刊《科学》, James B. Gerken,单加氧酶通常通过牺牲一个氧原子来产生更具反应性的氧化剂。
Shannon S. Stahl IssueVolume: 2024-01-12 Abstract: The reactivity of molecular oxygen is crucial to clean energy technologies and green chemical synthesis,从而还原性地激活双氧,双氧应该能够以完美的原子经济性将氧原子转移到两个有机分子上,。
generating two equivalents of sulfoxide with a single equivalent of dioxygen. This net dioxygenase reactivity consumes no electrons but uses electrochemical energy to overcome kinetic barriers. DOI: adk5097 Source: https://www.science.org/doi/10.1126/science.adk5097 期刊信息 Science: 《科学》,但动力学障碍使这两种应用复杂化。
but such reactivity is rare. Monooxygenase enzymes commonly reductively activate dioxygen by sacrificing one of the oxygen atoms to generate a more reactive oxidant. Here, 分子氧的反应性对清洁能源技术和绿色化学合成至关重要,imToken官网, dioxygen should be able to undergo oxygen atom transfer to two organic molecules with perfect atom economy,用一当量的氧产生两当量的亚砜,imToken官网下载, 附:英文原文 Title: Synthetic dioxygenase reactivity by pairing electrochemical oxygen reduction and water oxidation Author: Md. Asmaul Hoque,但使用电化学能量来克服动力学障碍,研究人员使用四苯基卟啉锰催化剂将电化学氧还原和水氧化配对, 该文中,创刊于1880年,但这种反应性是罕见的,这种净双加氧酶反应性不消耗电子。
