Reductive homocoupling of aromatic aldehydes and ketones has been achieved in tetrahydrofuran at room temperature using a catalytic amount of InCl3 (0.005–0.1 molar amount) under nitrogen atmosphere in the presence of both chlorotrimethylsilane and magnesium metal (Mg turnings) to provide the corresponding 1,2-diols in good to moderate yields with a high diastereoselectivity.
