Abstract

We have used a combination of 13C and 205Tl NMR 2D exchange spectroscopy (EXSY) to study cyanide exchange reactions in an aqueous solution containing the recently established complexes Tl(13CN)3 and Tl(13 CN)4- , and H13CN Because of the well-resolved heteronuclear spin-spin couplings (up to 8 kHz), the system was considered to have six exchanging sites for 13C NMR and nine for 205Tl NMR. The employed method gave an overview of the dynamic processes at chemical equilibrium. It is shown that in such systems otherwise invisible kinetic information can be brought into light. The EXSY spectra were evaluated quantitatively for both nuclei, and rate constants were calculated for the different exchange pathways.
