## Abstract Methyl (__R__)‐glycidate (=methyl (__R__)‐oxiranecarboxylate; **2**) in superacidic trifluoromethanesulfonic acid medium reacts with electron‐rich arenes to give __α__‐hydroxy‐__β__‐arylpropanoate derivatives **3a**–**3f** with high stereospecificity. At the same time, the observed high

Trifluoromethanesulfonic acid (TFSA) catalyzed isobutane-isobutylene alkylation modified with trifluoroacetic acid (TFA) or water, was studied over a wide range of acidity (Ho: -10.1 to -14.1). The effect of the acidity of these nonoxidizing strong mixed acid systems on the alkylation, is reported.
