• 論文の詳細を見る

• Exchange processes of diastereotopic protons of α-chlorodibenzyl sulfides were observed by means of dynamic nuclear magnetic resonance. Polar effects of solvents and substituent effects on the ease of the exchange process of protons in <I>p</I>,<I>p</I>′-disubstituted α-chlorodibenzyl sulfides indicate that the process occurs with the dissociation of the compounds into benzylic cations and chloride ion. It is possible to measure the rates of ionic dissocation by observing the change in the line shape of signals in <SUP>1</SUP>H NMR spectra. The scope of the method is discussed.
