Description
The rates of quaternization of six CH3- or CD3-substituted pyridines in acetone at 250C with CH3I or CD3I were determined conductimetrically. The main results which are presented indicate that in all cases replacement of CH3 by CD3 causes a small acceleration. This secondary isotope effect could be due to steric and/or electronic components. These are estimated and the results are shown and discussed. (author)
