Abstract

Herein, the effects of an electric field on radicals are investigated for a set of model radicals with varying complexity. An electric field impacts the intrinsic philicity of a radical, as quantified by the global electrophilicity index, ω. The extent of change in philicity depends on the directionality and strength of the applied electric field and the dipole moment and polarizability of the radical.

2. Electrophilicity and Nucleophilicity Index for Radicals

Abstract

Radicals can be regarded as electrophilic/nucleophilic, depending on their tendency to attack sites of relatively higher/lower electron density. In this paper, an electrophilicity scale, global as well as local, and a nucleophilicity scale for 35 radicals is reported. The global electrophilicity scale correlates well with the nucleophilicity scale, suggesting that these concepts are inversely related.
