Ru(II)-catalyzed intermolecular ortho-CâH amidation of weakly coordinating aromatic ketones with sulfonyl azides is reported. The developed reaction protocol can be extended to various substituted aromatic ketones to afford a wide range of desired CâN bond formation products in good yields.

give a fluorinated cyclopropylcarbinyl cation and a further Wagner-Meerweinrearrangement to generate a cyclobutyl carbocation, which undergoes intramolecular nucleophilic capture by amide to forge fluorinated cyclobuta[b]indoline derivatives. A polycyclic multi-fluorinated byproduct was also formed through a Ritter-type reaction in some cases.
已经开发了无催化剂的邻-磺酰胺系的亚烷基亚环丙烷的分子内双核氨基氟化。通过与的Selectfluor两个SET过程进行该反应,得到氟化cyclopropylcarbinyl阳离子和进一步瓦格纳米尔文重排,以生成碳正离子环丁基,其通过酰胺进行分子内亲核捕获伪造氟化cyclobuta [ b ]二氢吲哚衍生物。在某些情况下,还通过Ritter型反应形成多环多氟化副产物。

We report the sustainable and efficient synthesis of a new type of quinoline derivatives bearing one or two SO2CF3 groups. The protocol is metal-, catalyst- and irradiation-free, involves the use of readily available and stable precursors, and avoids the formation of side products. Also, the mild conditions of the process allow the tolerance of a wide range of functional groups.
