  amination of arene through C–H bond cleavage employing N-fluorobenzenesulfonimide (NFSI) as the amination reagent in good to excellent yields with broad arene scope in the absence of any metal, ligand or additive is reported. Unlike previous transition metal-catalysed aminations in which high reaction temperatures are usually necessary, this novel reaction at room temperature is the first example of C–H

  Oxidation of benzylic and allylic alcohols with chemical manganese dioxide smoothly proceeded under mild reaction conditions to give the corresponding aldehydes and ketones, respectively, in high yields. It is well-known that activated manganese dioxide (MnO2) is a useful reagent both for selective oxidation of benzylic and allylic alcohols to aldehydes and ketones, respectively, and for dehydrogenation

  苯甲醇和烯丙醇与化学二氧化锰的氧化在温和的反应条件下顺利进行，分别以高产率得到相应的醛和酮。众所周知，活化的二氧化锰 (MnO2) 是一种有用的试剂，可分别用于将苯甲醇和烯丙醇选择性氧化成醛和酮，以及将杂环脱氢成杂芳烃。1 虽然已经报道了几种制备活化 MnO2 的方法，但 2 制备非常繁琐，有时氧化效率缺乏重现性。也可以使用市售的活化MnO 2 ，​​但其活性也有很大差异。我们已经报道了化学二氧化锰 (CMD), 3 用于干电池制造，可有效用于某些烯丙醇 4 的氧化和杂环的脱氢，例如噻唑啉、5 2,3-二氢呋喃、6 3-吡咯啉、7 和 2-吡咯啉。8 沿着这条路线的进一步研究表明，CMD 广泛适用于将苄醇和烯丙醇 1 分别选择性氧化为醛和酮 2，如方案 1 所示。

  Kharasch-Sosnovsky reaction, the oxidation of oxazolines and thiazolines bearing a variety of 2-alkyl substituents (chiral and achiral) were smoothly oxidized to their corresponding oxazoles and thiazoles, respectively. The key feature involved in the successful implementation of this important oxidation was the use of a mixture of Cu(I) and Cu(II) salts to enhance the oxidation of the intermediate captodative

  使用Kharasch-Sosnovsky反应的改进，将带有各种2-烷基取代基（手性和非手性）的恶唑啉和噻唑啉的氧化分别平滑地氧化为相应的恶唑和噻唑。成功实施此重要氧化反应的关键特征是使用Cu（I）和Cu（II）盐的混合物来增强中间俘虏性自由基的氧化作用24。氧化失败的原因是在C-4处缺少碳烷氧基的恶唑啉/噻唑啉。

  Direct C5‐alkylation of oxazole/thiazole with ether or cycloalkane has been achieved through a cobalt‐catalyzed cross‐dehydrogenative coupling (CDC) process in moderate to good yields. This transformation represents the first C(sp2)−C(sp3) cross‐coupling at the C5‐position of the oxazole/thiazole via double C−H bond cleavages. Various functional groups on oxazole/thiazole substrates, as well as water

  通过钴催化的交叉脱氢偶联（CDC）工艺，恶唑/噻唑与醚或环烷烃直接进行C5-烷基化反应，产率中等至良好。这种转变代表通过双CH键断裂在恶唑/噻唑的C5位上的第一个C（sp 2）-C（sp 3）交叉偶联。简明实用的方案很好地耐受了恶唑/噻唑底物上的各种官能团，以及水和空气，构成了直接进入具有重要医学意义的杂环的方法。还提出了涉及激进过程的初步机制。
