Stereospecificity and mechanism in cation radical Diels-Alder and cyclobutanation reactions.
[reaction: see text] The cation radical Diels-Alder and cyclobutanation reactions of cis- and trans-1,2-(diaryloxy)ethenes with a cyclic and an acyclic diene have been found to be stereospecific, in accord with a concerted cycloaddition mechanism.
