  Identical acyl transfer reactions between pyridine N-oxides and their N-acylonium salts

  摘要：

  28 identical acyl exchange reactions R-CO-Nu(+), X- + Nu between pyridine N-oxides in acetonitrile were studied. Here, X- = BP and R = methyl, N,N-dimethylamino, N,N-diethylamino, 4-morpholino, 1-piperidino, N-methyl, N-phenylamino, or N,N-diphenylamino group. The IR and NMR spectroscopic characteristics of acyloxypyridinium salts were determined, and the quantum-chemical parameters of all reagents calculated. The results were subjected to correlation analysis. It was found that the rate of identical acyl transfer reactions was controlled by the interaction of frontier orbitals in the transition state.
