In the hexane extract of seeds of Platonia insignis Mart (known as "bacuri") has been isolated a tautomeric
form polycyclic polyprenylated acylphloroglucinol called garcinielliptone FC (GFC, Fig.
21-23), (51) Furthermore, for carbonyl compounds with an [alpha]-proton, a tautomeric
equilibrium can exist between the imine and the enamine, but in which the imine form predominates.
This metabolite, or its tautomeric
aldehyde, aldophosphamide, split spontaneously to form two other cytostatic compounds, phosphoramide mustard an acrolein (Wingaarden et al.
This was presumed until recently to occur by keto-enol tautomeric
racemization of the Sand R-enantiomers of 2-keto-3-methylvaleric acid.
Compatibility of thermodynamic models versus spectrofluorometric probe methods for tautomeric
solutes dissolved in binary mixtures.
Filter will calculate physicochemical properties for compounds in the ChemSpider repository, while Quacpac will allow the normalization of protomeric and tautomeric
It is known that acid-base indicators exist in equilibrium between two tautomeric
forms and the ratio of the two forms depend on the concentration of hydrogen ions in the medium.
Zinc(II) N2S2 Schiff-base complexes incorporating pyrazole: syntheses, characterization, tautomeric
equilibria and racemization kinetics, J.
We focused on valence tautomeric
complexes, 35),36) and found that several Co compounds show photo-induced magnetization effects because of the long-lived LMCT.
In solution, thiosemicarbazone molecules can exist in thione--thiol tautomeric
An interesting idea is using a free radical redox initiator system with a reducing agent that is present in the aqueous solution in at least two tautomeric
forms in equilibrium with one another (for example amino-iminomethanesulfinic acid and/or the salts thereof).
As it is well known that the equilibrium constant of the tautomeric
