    • Definition of a nucleophilicity scale 
      Jaramillo, Paula; Domingo, Luis R.; Contreras Ramos, Renato; Tiznado Vásquez, William; Fuentealba Rosas, Patricio (AMER CHEMICAL SOC, 2006-07-06)
      This work deals with exploring some empirical scales of nucleophilicity. We have started evaluating the experimental indices of nucleophilicity proposed by Legon and Millen on the basis of the measure of the force constants ...
    • Nucleophilicity scale for n- and pi-nucleophiles 
      Jaramillo, Paula; Fuentealba Rosas, Patricio; Pérez López, Patricia (ELSEVIER, 2006-08-31)
      A recently introduced empirical nucleophilicity index for a series of n- and pi-nucleophiles was evaluated. The index is based on the frontier molecular orbital information of the nucleophile and its electrophilic partner. ...
    • Towards an intrinsic nucleofugality scale: The leaving group (LG) ability in CH(3)LG model system 
      Jaramillo, Paula; Domingo, Luis R.; Pérez López, Patricia (ELSEVIER, 2006-03-10)
      For an important class of organic reactions in which a fragment of the reactants, the leaving group (LG) or nucleofuge (Z), is detached of the substrate bearing the bonding electron pair, the global electrophilicity index ...
