This grant in the Organic and Macromolecular Chemistry Program                  supports research of Prof. Reuben Rieke, University of                          Nebraska, which is concerned with new chemical reactions of                     mono- and biscarbonylmetal complexes of arenes and                              arene-substituted olefins.  Of particular interest will be                      analysis of the reactions of the complex dianions with a                        variety of electrophiles, because these hold the potential for                  evolving into useful new synthetic methodologies for complex                    organic synthesis.                                                                                                                                              The studies on bis-complexes will concentrate on biphenyl and                   other conjugated diarene systems.  The conjugated bis-complexes                 show the unusual reduction characteristics of one electron per                  chromium tricarbonyl unit, to give stable dianions.  Reaction                   with primary halides gives high yields to only the ortho                        product.  The mechanistic origins of this regioselectivity will                 be determined and its utility in new synthetic methodologies                    will be explored.  New mixed metal bis-complex systems of                       arene-substituted olefins will also be prepared, which should                   lead to stable dianions upon reduction.  The reactions of these                 dianions with electrophiles offer opportunities for control of                  regioselectivity between the arene and olefin portions of the                   molecule.  A variety of electrochemical and stereochemical                      techniques will be used to probe the reaction mechanisms of                     these reactions.
