Duong, Vincent K.; Horan, Alexandra M.; McGarrigle, Eoghan M. published the artcile< Synthesis of Pyridylsulfonium Salts and Their Application in the Formation of Functionalized Bipyridines>, Recommanded Product: 2-Bromo-N,N-dimethylpyridin-4-amine, the main research area is pyridylsulfide diphenyliodonium triflate copper selective arylation; pyridylsulfonium trifluoromethanesulfonate preparation; halopyridine organolithium pyridylsulfonium coupling; bipyridine preparation.
An S-selective 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 methodol. permits selective introduction of functional groups from com. available pyridyl halides, furnishing sym. and unsym. 2,2′- and 2,3′-bipyridines. Iterative application of the methodol. enabled the synthesis of a functionalized terpyridine with three different pyridine components.
