The absolute rate constant for the addition of pivaloyl radical to protonated benzothiazole is determined by evaluating the ratio of decarbonylation and aromatic attack. The high rate constant (7.1 × 105 l mol–1 s–1 at 5 °C) is discussed in terms of polar effects and a divergence from the classical reactivity: selectivity relationship is suggested.

Abstract

The absolute rate constant for the addition of pivaloyl radical to protonated benzothiazole is determined by evaluating the ratio of decarbonylation and aromatic attack. The high rate constant (7.1 × 105 l mol–1 s–1 at 5 °C) is discussed in terms of polar effects and a divergence from the classical reactivity: selectivity relationship is suggested.
