Abstract

6a HH 6b 4 em-and endo-1-bromocycloprop [2, 3] indenes (2 and 3) are formed via the cyclopropylcarbinyl radical intermediate 6a, resulting from initial abstraction of a hydrogen atom from the 1 position of cycloprop [2, 3] indene. 1-Bromomethylindene (4) results via bromine attack on the rearranged allylcarbinyl radical 6b. Finally, a probable pathway for the formation of naphthalene is via reaction of the allylcarbinyl radical 6c with bromine to give ...
