Abstract
The equilibrium constants or acetyl transfer between O-acetylonium salts of a series of pyridine N-oxides and 4-(4-dimethylaminostyryl)pyridine N-oxid e in acetonitrile and methylene chloride were determined. The equilibrium c onstants correlate with the acid-base characteristics of the N-oxides and w ith the heats of reactions calculated quantum-chemically.
