Conclusions
-
1.
The authors have investigated the reversible transfer of a proton from the hydroxyl group of 3,6-di-tert-butyl-2-hydroxyphenoxyl to diethylamine.
-
2.
They have discovered and investigated proton exchange between the radical and primary and secondary amines. On the basis of the experimental data they suggested a mechanism for this exchange, involving the semiquinone radical anion as an intermediate compound.
