Graphical Abstract
  • characterization of 6 was achieved by X-ray analysis using a single crystal of 6a (Figure 2), and it was found that the iodoarylation products 6 have a seven-membered carbocycle bearing adjacent difluoromethylene and iodomethylene units. In addition, a selective HI elimination from 6a could be achieved by the
