Abstract

Direct spectroscopic observations were made of substituted ethylene dications bearing r- stabilizing groups such as an aryl, a hydroxy, or a methoxy group in a strong acid, trifluoromethanesulfonic acid (TFSA). Based on the spectroscopic evidence, we reached the following conclusions.(1) l, l-Diaryl-2-hydroxy-2-methoxyethylene dications, l, l-diary1-2, 2- dihydroxyethylene dications, and 1, 1, 2-triaryl-2-hydroxyethylene dications are discrete ...
