Brønsted relations with anomalous (less than zero) values for the α coefficient were obtained for the ionization reactions of monoalkylpyridines, monoalkylbiphenyls, and monoalkylbenzenes in solutions of the lithium (or potassium) tertbutoxide and dimethyl sulfoxide salts in DMSO and also in a solution of lithium cyclohexylamide in cyclohexylamine. The appearance of anomalous values of α is explained by features of the change in the structure of the anionic fragment of the CH acids and the effect of this process on the mechanism of the elementary event in the ionization reaction.
