The reaction of mono-aryl substituted methylenecyclobutanes with diphenyl diselenide in the presence of iodosobenzene diacetate and H2O

The mono-aryl substituted methylenecyclobutanes undergo an interesting reaction with diphenyl diselenide in the presence of iodosobenzene diacetate and H2O at 40 °C in 1,2-dichloroethane to give the corresponding aryl-(1-phenylselanylcyclobutyl)methanones in moderate to good yields within 30 h. A plausible reaction mechanism has been discussed on the basis of the control and 18O-labeling experiments.
