Abstract

The interaction between the weak CH-acid CF3CH2NO2 and aliphatic amines has been studied by NMR in CDCl3 and CFCl3 solutions. It is shown that no measurable amounts of H-bonded complexes are formed. However, reversible proton transfer with the formation of ion pairs takes place. The kinetic parameters of this process have been determined.

Abstract

Методом ЯМР изучено взаимодействие слабой CH-кислоты CF3CH2NO2 с алифатическими аминами в CDCl3 и CFCl3. Показано, что при этом не образуется измеримого количества комплексов с водородной связью, однако происходит переход протона с образованием ионных пар. Получены кинетические параметры этого процесса.
