摘要

The base-catalyzed proton migration (from the 7-to 2-position) and proton exchange (at the 7-position) of cycloheptatrienes carrying an electron-withdrawing group were studied in a medium of aqueous sodium hydroxide or alcoholic potassium hydroxide. The order of the effect of the various substituents upon the relative rates is approximately: CN> CONH 2> COO−, Ph. The base-catalyzed prototropic isomerization proceeds through: i) the ...
