The title compounds were hydrogenolyzed over PdO or Raney nickel. The C//2-C//3 bond of the cyclopropane ring underwent cleavage exclusively over both catalyts. The contribution of the fluorine substituent to the lengthening and weakening the C//2-C//3 bond of the cyclopropane ring seems to become a dominant factor in regioselectivity.
