Metal ion-biomolecule interactions. Part 22. Cr(III)-catalyzed isotopic hydrogen exchange in methylimidazoles

The detritiation kinetics of the Cr(III) complexes 1 and 3-6 have been studied in aqueous buffers at 35degreeC, using the liquid scintillation counting technique. Results for 5 and 6 provide benchmark kinetic data for N-T/N-H exchange under the experimental conditions of the study and have aided in...

Summary:The detritiation kinetics of the Cr(III) complexes 1 and 3-6 have been studied in aqueous buffers at 35degreeC, using the liquid scintillation counting technique. Results for 5 and 6 provide benchmark kinetic data for N-T/N-H exchange under the experimental conditions of the study and have aided in the delineation of N-T/N-H from C-T/C-H exchange in the parallel reactions observed experimentally.
