Cycloheptatriene 9-cyanoanthracene

Other results in this area point to an initial [4 + 4] cycloaddition step followed by a themnally or photochemically initiated rearrangement of the initial cycloadduct to give a [4 + 2] species as the final observed pi ucL Irradiation of 9-cyanoanthracene and cycloheptatriene at low temperature initially produced the [4 -i- 4] adduct (106) which promptly rearranged to (107) at temperatures exceeding 0 C. Related diene-arene photocycloadditions have been reported in which comparable tandem processes were apparently operative. " ... [Pg.636]

Cycloheptatriene quenches the fluorescence of 9-cyanoanthracene and undergoes cycloaddition to give a mixture of + 2J and [ 4j + 4J cycloadducts together with other minor products. ... [Pg.206]
