note
-
Attempts to study the reaction in cyclohexane, hexane, and benzene failed because the reaction was too slow to measure even at the highest possible tetrabutylammonium cyanide concentrations (the fastest rate) in these solvents.

note

A conductivity study in our laboratories shows significant levels of cyanide ion pairs in both DMSO and THF. This suggests the reacting cyanide ion is the same in both solvents.

α bond in the transition state would also lead to some shortening of the N≡C bond and a smaller, not the larger, KIE that is observed in THF. However, the change in the very small secondary nitrogen KIE of approximately 0.1% is very small and probably does not represent a significant change in the KIE and transition state structure at the nitrogen.
