Abstract:
Photofragmentation of substituted 1-methylene-1,2,2a,10b-tetrahydrocyclobuta[l]phenanthrenes, under ambient conditions in solution, produces the corresponding allenes with the concomitant formation of phenanthrene. These phenanthrene-based precursors offer a new and general photochemical route to allenes including, potentially, strained cyclic allenes.

Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
