Abstract
A four-member ring hypervalent iodine radical has been detected in the lase r flash photolysis of 1,3-diiodo-1,3-diphenylpropane. This species absorbs at 320 nn, has a lifetime of similar to 9.5 mu s in cyclohexane, and is not quenchable by oxygen. Excitation of this radical by means of laser-drop ph otolysis results the formation of trans-1,2-diphenylcyclopropane through co ncerted iodine extrusion.
