the visible light spectrum. The synergic effect of ARS and TiO2 in the photocatalyst system has catalyzed direct C–H functionalization of sp2 C–H bonds toward thiocyanation and cyclization reactions. Several aromatic and heteroaromatic scaffolds (2-phenylamino-thiazole, phenol, aniline, indole and pyrrole derivatives) were treated with the thiocyanate anion at room temperature. Herein, the first report
similar to the atomic radius to oxygen, and lower electronegativity and ionization energy than the O atom. Therefore, the N doping converts ZnO into the p-type ZnO semiconductor structure. This potent, simple, and versatile protocol afforded thiocyanation reactions of indole and phenols under visible light. The reactions proceeded through a radical pathway by applying air molecular oxygen as a low cost
在这项研究中,氮掺杂的 ZnO 纳米棒 (N-ZnO NRs) 通过非常简单的水热过程合成,充分表征,并且该光催化剂在室温下可见光照射下成功地用于吲哚和苯酚的硫氰化反应。两类重要的芳香族化合物吲哚和酚类使用 N-ZnO NRs 作为光催化剂,用硫氰酸铵作为硫氰化剂处理,以良好的产率形成相应的硫氰基化合物。氮是最合适的 p 型掺杂剂之一,它无毒,与氧的原子半径相似,电负性和电离能低于 O 原子。因此,N掺杂将ZnO转化为p型ZnO半导体结构。这个强大的,简单的,和通用方案提供了可见光下吲哚和酚的硫氰化反应。该反应通过使用空气分子氧作为低成本和环境友好的末端氧化剂通过自由基途径进行。彻底描述了基于控制实验的建议机制。
