(Chemical Equation Presented) 2, 3-Dihydro-1, 4-benzodioxins can be prepared in a tandem one-pot procedure by reaction of o-iodophenols with epoxides catalyzed by Cu2O/1, 10-phenanthroline/Cs2CO 3 system. The reaction is suggested to occur via a novel ring-opening/coupling mechanism, giving moderate to good yields. Moreover, both aryl and aliphatic epoxides are tolerated under these conditions.
