Salicylic acid anion•The mechanisms of the decarboxylation of salicylic acid anion have been investigated.•The energy barriers in aqueous solution approximately declined by 25%–31% compared with gas phase.•Both the methyl and the nitro at theorthoposition of the carboxylate group can reduce...
Kinetics and mechanism of decarboxylation of some pyridinecarboxylic acids in aqueous solution - Dunn - 1976 () Citation Context ...us or enzyme assisted. The evidence for spontaneity of QAMN decarboxylation is based on the elevated rates of spontaneous decarboxylation observed for 1- and 3-...
Co-ordination to chromium (III) has been found to mask the bromodecarboxylation of salicylic acid, with the rate for the ligand being at least 600 times that of the complex. The rate of monobromination of salicylic acid has been found to be extremely rapid, with a minimum second order ...
It is therefore concluded that the mechanism proposed in Part I of this series involves three steps: ionization of the salicylic acid to a quinolinium salicylate ion pair, reversible protonation by quinolinium ion of the salicylate ion at carbon 1 of the aromatic ring, and loss of carbon ...
The mechanisms of the decarboxylation of salicylic acid anion and its ortho substituted derivatives in gas phase and aqueous solution have been investigated by B3LYP method of DFT theory using the 6-31++G (d,p) basis set. The decarboxylation process includes hydrogen transfers from hydroxyl to ...
