摘要:
TransFer of' acyl groups from N-acyloxypyridinium salts to pyridine N-oxides in acetonitrile was studied. The equilibrium constants of' acyl exchange were determined. These quantities vary in the range coverino ei,,ht orders of magnituJe, depending on the structure of the reavents. and are independent of' the z' c C C structure ol'the acyl group.
