Table 3. Iron(III)-Catalyzed Unsymmetrical Etherification of Two Different Alcohols^a.

^aReaction conditions: secondary alcohol (0.5 mmol), primary alcohol (0.5 mmol), Fe(OTf)₃ (0.025 mmol, 5 mol %), and NH₄Cl (0.025 mmol, 5 mol %) in DCM (2 mL) were heated at 45 °C for indicated time.

^bFe(NO₃)₃·9H₂O (0.025 mmol, 5 mol %) was used as catalyst.

^cReaction was carried out at 70 °C. Reported yields correspond to isolated product after column chromatographic purification.
