Abstract:
The equilibrium constants for the ion-pair formation between 2,4-dinitrophenol and the following amines: pyrrolidine, piperidine, dibutylamine, di-isopropylamine, cyclohexylisopropylamine, dicyclohexylamine, morpholine, and diethylamine, in tetrahydrofuran (THF) have been measured. The relative acidities of the same amines (except diethylamine) have been also determined, as well as the pKa-values for di-isopropylamine, cyclohexylisopropylamine, and dicyclohexylamine in THF. The results show the importance of acid-base equilibria in determining the product distribution in the carbonylation of lithium amides in THF. They also explain the role of the [amine]:[amide] ratio in determining the reaction products.
