Synthesis of new amphiphilic perfluoroalkylated bipyridines
摘要:
General and versatile synthetic methods have been developed for the preparation of a large variety of 2,2'-bipyridines bearing two various perfluoroalkylated side chains with an ester or a methylene junction in the 4,4'-positions, e.g., 4,4'-bis[[2"-(F-alkyl)ethenyl]alkyl]-2,2'-bipyridines, 4,4'-bis[[[(F-alkyl)alkyl]oxy]carbonyl]-2,2'-bipyridines, and 4,4'-bis[[[[2"-(F-alkyl)ethenyl]alkyl]oxy]carbonyl]-2,2'-bipyridines.
