- Abstract
Imidazolium fluorochromate (IFC) oxidation of 11 meta- and para-substituted benzylamines, in varying mole fractions of benzene/2-methylpropan-2-ol binary mixtures, is first order in IFC and acid and zero order in substrate. The Hammett correlation yielded a U-shaped curve, indicating a change in the relative importance of bond formation and bond fission in the transition state. The rate data failed to correlate with macroscopic solvent parameters such as ℇr and E<STACK>TN</STACK>. The correlation of kobs with Kamlet–Taft solvatochromic parameters suggests that H-bonding between the reacting species and the solvent plays a major role in governing the reactivity. © 2010 Wiley Periodicals, Inc.
