ChemInform Abstract: A Mild and Convenient One-Pot Two-Step Synthesis of Hydroxyiminodihydrobenzofurans Mediated by Silica Gel under Microwave Activation Conditions.
An AICl3–ZnCl2 mixture supported on silica gel is found to be an efficient medium for the Fries rearrangement of acyloxybenzene or naphthalene derivatives in solvent-free conditions under microwave irradiation.
