Abstract
PROF. INGOLD and his co-workers have shown that an exchange of hydrogen atoms can take place between benzene and sulphuric acid, the latter containing heavy hydrogen atoms as indicator. Prof. Polanyi and Dr. J. Horiuti suggest as a general mechanism for hydrogen exchange in unsaturated compounds, the addition and subsequent elimination of water, or other simple hydrogen-containing molecule. Prof. Ingold and his co-workers admit this mechanism in the case of ordinary unsaturated compounds, but with benzene they assume the addition and subsequent elimination of sulphuric acid, the molecules of which are rearranged (‘polarised’) in the process.
