Reaction Involving Hydrogen and Group Translocations

However, a large excess (80 equiv.) of acrylonitrile had to be used in order to repress the normal Barton reaction (e.g., the coupling of the nitrosyl radical generated during the photolysis to the 5-hydroxy radical). 

A reaction sequence where the alkoxyl radical is obtained from benzensul-fonates such as 175, leads to the formation of hnear addition products [165, 166].
