摘要

Abstract: A nitrogen kinetic isotope effect ki4/klS= 1.0019 i 0, 0001, a deuterium kinetic isotope effect kHj/kDJ= 0.83 & 0.04, and a solvent deuterium isotope effect kH/kD= 1.00* 0.05 were measured on the Menschutkin reaction between methyl iodide and N, N-dimethyl- p-toluidine at 25 OC in methanol. Semiempirical quantum mechanical calculations of kinetic isotope effects of deuterium, carbon, and nitrogen on the same reaction were performed ...
