Abstract

The reaction of arylmethylidenecyclopropylcarbinols 1 with iodine in the presence of potassium carbonate or diphenyldi­selenide in the presence of sulfuryl chloride stereoselectively gives ring-closure product 1-iodo-2-aryl-3-oxabicyclo[3.1.0]hexane or 1-phenylselenenyl-2-aryl-3-oxabicyclo[3.1.0]hexane in good to high yields at room temperature. A plausible reaction mechanism has been proposed.
