Facile Pyridine S(N)Ar Reactions via N-Phosphonium–Pyridinium Intermediates
Here we report that N-phosphonium pyridinium intermediates are unusually reactive for pyridine S(N)Ar reactions. Specifically, forming phosphonium salts from halopyridines typically requires elevated temperatures and Lewis acid additives. The alternative activation mode described in this paper permi...
