Uv irradiation of a cyclohexane solution of 2-fluoro-1-indanone, 2-fluoro-1-tetralone, or 2-fluoro-1-benzosuberone resulted in the formation of a radical product (1-indanone, 1-tetralone, or 1-benzosuberone), and the degree of conversion depended on the ring size of the cycloalkanone. On the other hand, both radical as well as ionic products were formed when 2-bromo-2-fluoro derivatives of 1-indanone, 1-tetralone, or 1-benzosuberone were irradiated.
