摘要：

2-Oxy-3-(pyridinium-1'-yl)-1,4-naphthoquinone betaines are obtained in moderate to good yield by oxidation of 1,4-naphthoquinones with, iodine/MnO2 or hydrogen peroxide in the presence of substituted pyridines. Pyridinium-l,4-naphthoquinone iodides and 2,3-epoxy-2,3-dihydronaphthoquinone are suggested intermediates.
