Abstract

Under the 9, 10-dicyanoanthracene-sensitized photoinduced electron-transfer conditions,(Z, Z)-,(E, E)-,(E, Z)-3, 6-diaryl-2, 6-octadiene and (d, l),(meso)-2, 5-diaryl-3, 4-dimethyl-1, 5- hexadiene stereospecifically undergo the Cope rearrangement to give a Cope photostationary mixture. Remarkably, the photoinduced electron-transfer Cope rearrangements of the 4-methylphenyl derivatives are concurrent with the formation of ...
