The title radical rotamers were generated by thermolyses of the corresponding t-butyl peroxycarboxylates or photolyses of the corresponding 2(1H)-thioxo-1-pyridyl carboxylates. Products from the t-butyl peroxyesters were t-butoxy compounds, dimers, and colligation products with a benzyl radical, when the reactions were carried out in toluene. In carbon tetrachloride, chlorine-abstraction products and
