1971 C. J. Gray Enzyme-catalysed Reactions i. 21 The nucleophilicity of the small fluoride ion is higher in non-hydroxyl solvents where the solvation is less effective.

1990 Science 13 July 107/2 Methylation rates for the different halogens varied but were consistent with the known nucleophilicities of the acceptor anions.
