摘要

Abstract: The reactivity of protonated and methylated methyl ester in superacidic media was investigated by experiment and theory. Protonated methyl acetate was found to undergo slow acyl oxygen cleavage even at-78" C in FS03WSbF# 02 solution to give acetyl cation and methyloxonium ion. 1, l-Dimethoxyethyl cation (methylated methyl acetate) was found to undergo slow methyl exchange in CD3S03F/SbF5 solution. The reaction of 1, l- ...
