Abstract

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, ie, 1, 2-aryl or alkyl migration across the double bond and 1, 2-hydride or methyl migration to the cationic center.
