Relationship between nucleophilicity/electrophilcity indices and reaction mechanisms for the nucleophilic substitution reactions of carbonyl compounds
(John Wiley and Sons Ltd, 2004)
Theoretical electrophilicity and nucleophilicity scales, defined in terms of electronic reactivity indices, were tested for the reaction of a series of carbonates with neutral and charged reagents of varying nucleophilicity. ...
Mechanistic pathways of aromatic nucleophilic substitution in conventional solvents and ionic liquids
(Royal Society of Chemistry, 2014)
Solvation effects on the reaction mechanism of the title reactions have been kinetically evaluated in 21 conventional solvents and 17 ionic liquids. Solvent polarity affects the catalyzed and non-catalyzed SNAr pathways ...
