Photolysis of 1,2-benzo-1,3-cycloalkadien-4-yl bromides and 1,2-benzo-,1,3-cycloalkadien-3-yl chlorides showed a remarkable effect of ring size on the rearrangements of the resulting 1,2-benzo-1,3-cycloalkadienyl cations, i.e., 1,2-aryl or alkyl migration across the double bond and 1,2-hydride or methyl migration to the cationic center.
