Pirkle, William H. Shvets, Aleksey 2015-09-25T22:12:43Z 2015-09-25T22:12:43Z 10000-01-01 2002 2002 The work described in Chapter 6 is of a mechanistic nature. Identification of the formation of Meisenheimer complexes under conditions of phase transfer catalysis helped to rationalize the enantioselectivity observed in these systems. Quaternary ammonium cations are identified as stabilizing factors for the negatively charged Meisenheimer complexes in non-polar organic solvents. The gained mechanistic insight allowed the development of the first enantioselective nucleophilic aromatic substitution reactions. Made available in DSpace on 2015-09-25T22:12:43Z (GMT).
