(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.
An evidence for remarkable difference of the electrophilicity between two carbonyl groups in the photoexcited 1,2-naphthoquinone. Photocycloaddition reaction of 1,2-naphthoquinone with olefins
