Abstract
The ortho Claisen rearrangement of dissymmetrical, 1,4-diaryloxy-trans-2-butenes has been studied. Degradative evidence was provided to determine the migratory aptitude of the aryl moieties. An ortho substituent on the aryl ring induced greater ease of migration. Para chloro and para methyl functions induced nearly equal migratory aptitude.
