Reaction of 2,2-difluorostyrenes and sodium chlorodifluoroacetate in diglyme solution at 180 degrees C gave 1-aryl-2,2,3,3-tetrafluorocyclopropane as a primary product. After prolong reaction under the same condition, the 1, 1,2,2-tetrafluoroindanes can be isolated as the only product in good yields. All the tetrafluorocyclopropanes and tetrafluoroindanes were well characterized by spectroscopic analyses. (c) 2006 Elsevier Ltd. All rights reserved.
