Abstract
The C-11/C-14 kinetic isotope effect (KIE) has been used to probe ster ic hindrance in the Menshutkin reactions of different substituted amin es with labeled methyl iodide. The KIEs for the reaction of 2,6-lutidi ne and 2,4-lutidine with labeled methyl iodide in acetonitrile were de termined to 1.220 +/- 0.009 and 1.189 +/- 0.012, respectively. The C-1 1/C-14 KIEs for the reaction of triethylamine and quinuclidine, with l abeled methyl iodide in 1,2-dimethoxyethane were determined to 1.221 /- 0.006 and 1.220 +/- 0.005, respectively.
