  A Convergent Route to Geminal Difluorosulfides and to Functionalized Difluorothiochromans, a New Family of Organofluorine Compounds

  摘要：

  The synthesis of the novel O-ethyl-S-(4-chlorophenylthio)difluoromethyl xanthate and its radical addition to various terminal alkenes are described. The geminal difluorosulfide adducts undergo closure onto the aromatic ring by further treatment with peroxide to furnish difluorothiochromans, a new family of organofluorine compounds.

• Radical Instability in Aid of Efficiency: A Powerful Route to Highly Functional MIDA Boronates

  日期：2015.6.3

  The inability of the sp(3) boron in MIDA boronates to stabilize an adjacent radical makes possible the efficient addition of a wide array Of xanthates to vinyl MIDA boronate, leading to highly functionalized and diverse aliphatic organoboron structures. The lack of radical Stabilization also allows the exchange Of the Xanthate in the adducts with a bromine. In one case, the bromine was substituted to generate a cyclopropyl MIDA derivative.
