Fluorous 2-Chloropyridinium Salt (Mukaiyama Condensation Reagent) for Amide Formation Reactions.

Tadamichi Nagashima1, Yimin Lu, Michael J Petro, Wei Zhang.   

Abstract

A new fluorous 2-chloropyridinium hexafluorophosphate was prepared as a modified Mukaiyama condensation reagent, and it was applied in amide formation reactions. Good to excellent purities of amides were obtained after fluorous solid-phase extraction of reaction mixtures without additional chromatography.
