Studies on decarboxylation reactions. Part 4. Kinetic study of the decarboxylation of some N-alkyl- or N-phenyl-substituted 5-amino-1,3,4-oxadiazole-2-carboxylic acids
Abstract
The rate constants of the decarboxylation reaction of compounds (Ib–f) have been measured in water over a range of proton activities, at various temperatures. The results obtained strongly support the unimolecular decarboxyprotonation mechanism.
