%X The 3&#946;,5-cyclo-5&#946;-cholestan-6-yl radical (6), generated by interaction of triphenylstannane with 6&#946;-chloro-3&#946;,5-cyclo-5&#946;-cholestane (12), undergoes &#946;-scission by specific fission of the 4,5-bond to give the thermodynamically less stable possible radical product (8). The results of these and earlier experiments indicate that &#946;-scission of cyclopropylcarbinyl radicals is under stereoelectronic control, and involves a transition state formed by primary interaction of the semi-occupied orbital with a &#946;&#947;-&#963;* orbital.
