chelation-assisted C–H arylation reaction of benzo[h]quinoline is described. This transformation, using [RuCl2(p-cymene)]2 as the catalyst and cheap and easily accessible arylsulfonylchlorides as the arylation source, featured simple reaction conditions, a broad substrate scope, and functional group tolerance. The successful application of some bioactive-molecule-based sulfonyl chlorides further highlighted
在此,描述了苯并[h]喹啉的新型螯合辅助 C-H 芳基化反应。该转化以[RuCl 2 ( p -cymene)] 2为催化剂,廉价易得的芳基磺酰氯为芳基化源,具有反应条件简单、底物范围广、官能团耐受性高等特点。一些基于生物活性分子的磺酰氯的成功应用进一步突出了这种脱硫 C-H 芳基化方案的潜在用途和重要性。

Rhodium(I)-catalyzed hydroarylative cyclization of 1,6-diynes with three distinct classes of arenes has been realized, enabling highly enantioselective synthesis of a broad range of axially chiral 1,3-dienes that are conformationally labile. Detailed mechanistic studies have been explored by experimental and computational methods.
