参考标题:Synthesis Of Pyridylsulfonium Salts And Their Application In The Formation Of Functionalized Bipyridines 作者:Vincent K. Duong,Alexandra M. Horan,Eoghan M. Mcgarrigle |发布日期:2020.11.6 摘要:Arylation Of Pyridylsulfides With Good Functional Group Tolerance Was Developed. To Demonstrate Synthetic Utility, The Resulting Pyridylsulfonium Salts Were Used In A Scalable Transition-Metal-Free Coupling Protocol, Yielding Functionalized Bipyridines With Extensive Functional Group Tolerance. This Modular Methodology Permits Selective Introduction Of Functional Groups From Commercially Available Pyridyl
