The determination of the secondary ..alpha..-deuterium kinetic isotope effect (..alpha..-DKIE) is reported for the reverse Menschutkin reactions of 1-methyl-3-chloropyridinium cation with iodide anion in the presence of excess triphenylphosphin (TPP) using both the direct CH/sub 3//CD/sub 3/ isotope shift method and the ordinary CH/sub 3/ and CD/sub 3/ separate run method. The potential utility of quantitative /sup 31/P NMR measurements for rate determinations is demonstrated. 25 references, 1 figure, 1 table.
