cycloadduct with hexachlorocyclopentadiene, indicative of a stereospecific process. The kinetic isotope effects for this reaction were also determined at natural abundance, and suggest a very asynchronous but concerted process. This conclusion is backed by comparison with theoretically calculated isotope effects.
