[2+2]-Cycloaddition reaction of styrene derivatives using an Fe(III) salt catalyst
Iron(III) perchlorate catalyzed cyclodimerization of trans-anethole gave trans, anti, trans-cyclobutane stereospecifically in good yield. Alumina supported iron(III) perchlorate was an especially efficient one-electron oxidation reagent.
