✦ Synopsis


The mechanism of the phototransposition reaction of a number of arylalkyl substituted indenes has been found to be markedly dependent on the nature and location of the substituent groups. Considerable interest has been focused in recent years on phototransposition reactions which have the net effect of interchanging atoms within a five-membered ring'. Examples have been reported for variously substituted heterocycles2 and cyclopentadiene derivatives3. Bicyclo[2.l.O]pent-2-enes and 3-vinylcyclopropene analogs are the most commonly invoked intermediates responsible for these rearrangements; in some instances, such molecules have been detected and characterized.' Recently, we described the photochemical rearrangement of indenes
