摘要：

The kinetic parameters of the fast reversible reaction of proton transfer between paramagnetic proton donors: 3,6-di-tert-butyl-2-hydroxyphenoxyl, 4,6-di-tert-butyl-3-chloro-2-hydroxyphenoxyl, 4-triphenylmethyl-6-tert-butyl-3-chloro-2-hydroxyphenoxyl, and paramagnetic proton acceptors, nitroxy radicals containing nitrogen heterocycles were estimated by EPR. It was found that proton transfer between paramagnetic acid and base takes place with a higher rate than the analogous reaction between substituted 2-hydroxyphenoxyl and a diamagnetic base.
