Arysulfonylallenes (ArSO2–CR1=C=CR2R3), depending on their structure, react with iodine to give two types of products, diiodo alkenes ArSO2–CHI–CI=CR2R3, when R1=H, or iodo dienes ArSO2–CR1=CI–C(Me)=CH2, when R1=Br, Ph and R2=R3=Me, in yields of 55–98%. The plausible reaction mechanisms have been proposed.
