Plot of initial rate versus THF concentration for the ortho-selective isotopic exchange of 0.32 M 4,4-dimethyl-2-phenyl-2-oxazoline (29) with 0.10 M NaDA and 0.79 M i-Pr2ND in hexane cosolvent at −40 °C. The curve depicts an unweighted least-squares fit to the function f(x) = ax + b: a = 0.09 ± 0.1; b = 6.8 ± 0.9.
