Abstract

The gas phase anion proton affinities of the periodinane anions IBX and IBA were examined using mass spectrometry-based experiments, and estimated as 1300 ± 25 and 1390 ± 10 kJ mol−1, respectively. The experimental results were supported by theoretical calculations, which yielded proton affinities of 1336 and 1392 kJ mol−1 for IBX and IBA respectively, at the B3LYP/aug-cc-PVDZ level of theory.
