Alkylphenols afford only O-acyl derivatives on treatment with γ-chlorobutyroyl chloride in the presence of both Et3N and AIC13 at 20–60 °C. They cyclize under the action of K2CO3 in DMSO into the respective cyclopropanes and undergo Fries rearrangement on heating with AICl3 at 120 °C into C-acyl derivatives.
