โœฆ Synopsis


The reaction of photoisomerization of norbornadiene and its derivatives to the corresponding quardricyclanes, brought about either by direct irradiation or triplet sensitization is well known (1). However, similar isomerizations involving the related bicyclo[2.2.2]octa-2,5-diene system are not known. Studies in this area have apparently led to

Altho,gh very prominant in bicycloC2.2.llheptadiene photochemistry; the difficulty of observing Cristol closure (internal 2 + 2 cycloaddition) with bicyclo[2.2.2]octodienes has been surprising to many workers.1 Recently, however, Prinzbach, Eberbach, and PhillipposianZ have isolated the Cristol clos
