A novel aldehydic C−H functionalization reaction between salicylaldehydes and sulfoxonium ylides has been developed under rhodium(III) catalysis, affording coupling products in moderate to good yields. A plausible mechanism involving aldehydic C(sp2)−H activation by rhodium(III) and rhodium(III) catalyzed carbene insertion is also proposed. It was also found that the aldehydic C−H functionalization
在铑(III)催化下,开发了水杨醛与亚磺酰之间的新型醛C-H官能化反应,可提供中等至良好收率的偶联产物。还提出了一种可能的机理,该机理涉及通过铑(III)和铑(III)催化的卡宾插入而使醛类的C(sp 2)-H活化。还发现醛化的CH功能化然后脱水环化能够在一锅中产生类黄酮。
