Eaton’s Reagent: A Less Viscous Alternative to PPA
No.146(August 2011)

Eaton’s reagent (1, phosphorus pentoxide - methanesulfonic acid solution in the ratio of 1:10 by weight) is used as an alternative to polyphosphoric acid (PPA) in organic synthesis. In addition its ease of handling, yields obtained with the Eaton’s are better than those obtained with PPA. Recently, the efficient cycloacylation of aniline derivatives to 4-quinolones, investigated as antibiotics, etc., was reported.1)
