| Abstract: | Using EPR the proton exchange between 3,6-di-tert-butyl-2-oxyphenoxyl, 4-triphenylmethyl-6-tert-butyl-3-chloro-2-hydroxyphenoxyl, and secondary amines was studied. The nature of the solvent had no effect on the kinetic parameters of the process which was attributed to the formation of strong complexes owing to ring type hydrogen bonds. The effect of prototropy on the mechanism of proton exchange was examined.A. I. Nesmeyanov Institute of Heteroorganic Compounds, Russian Academy of Sciences, 117813 Moscow.
