Abstract
Quasi-tetrahedral o-azophenylboronic acid (azoB-ROH), which contains the protic solvent ROH, is a key species in the colorimetric sensing of saccharides by o-azophenylboronic acid (azoB). In this study, we compared the reactivity of azoB-ROH with that of trigonal azoB and tetrahedral o-azophenylboronate (azoB-OH−), and clarified the reaction mechanism of azoB-ROH with cis-1,2-cyclopentanediol and D-glucose. Analysis of the kinetics of the reactions of azoB with cis-1,2-cyclopentanediol and D-glucose in DMSO:water = 1:9 and azoB with cis-1,2-cyclopentanediol in tetrahydrofuran containing a small amount of methanol revealed that there was not much difference in the reactivity of azoB-H2O and azoB-OH−, although the reactivity of azoB was higher than that of azoB-MeOH, that is, the reaction mechanism of azoB-H2O was essentially the same as that of azoB-OH−.
期刊介绍：
As the leading archival journal devoted exclusively to chemical kinetics, the International Journal of Chemical Kinetics publishes original research in gas phase, condensed phase, and polymer reaction kinetics, as well as biochemical and surface kinetics. The Journal seeks to be the primary archive for careful experimental measurements of reaction kinetics, in both simple and complex systems. The Journal also presents new developments in applied theoretical kinetics and publishes large kinetic models, and the algorithms and estimates used in these models. These include methods for handling the large reaction networks important in biochemistry, catalysis, and free radical chemistry. In addition, the Journal explores such topics as the quantitative relationships between molecular structure and chemical reactivity, organic/inorganic chemistry and reaction mechanisms, and the reactive chemistry at interfaces.
