Hydroquinone is readily oxidized by a (salen)ruthenium(vi) nitrido complex in the presence of pyridine to give benzoquinone. Experimental and computational studies suggest that the reaction occurs via a novel mechanism that involves an initial electrophilic attack at the aromatic ring of the hydroquinone by the nitrido ligand.
在吡啶存在下,对苯二酚很容易被(水杨醛缩邻苯二胺)钌(Ⅵ)氮化物配合物氧化生成苯醌。实验和计算研究表明,该反应通过一种新机制发生,该机制涉及氮化物配体对苯二酚芳环的初始亲电攻击。
