A kinetic study of the oxidation of α-hydroxy acids and α-hydroxy ketones by potassium bromate
The oxidation of α-hydroxy acids and α-hydroxy ketones by Br(V) follows the rate-law \documentclass{article}\pagestyle{empty}\begin{document}$$\frac{{- d[{\rm Br(V)}]}}{{dt}} = k_2 [{\rm Br(V)}][{\rm substrate}]$$\end{document}However, the former reaction exhibits a second-order dependence on hydrog...

| abstract |
The oxidation of α-hydroxy acids and α-hydroxy ketones by Br(V) follows the rate-law \documentclass{article}\pagestyle{empty}\begin{document}$$\frac{{- d[{\rm Br(V)}]}}{{dt}} = k_2 [{\rm Br(V)}][{\rm substrate}]$$\end{document}However, the former reaction exhibits a second-order dependence on hydrogen ion concentration while the latter reaction has a third-order dependence. A mechanism involving a slow formation of a bromate ester of the α-hydroxy acid followed by a fast decomposition is proposed. A rate-determining formation of a bromate ester from the conjugate acid of benzoin, followed by a rapid decomposition of the bromate ester, explains the kinetic data for the oxidation of benzoin. |

A mechanism involving a slow formation of a bromate ester of the α-hydroxy acid followed by a fast decomposition is proposed. A rate-determining formation of a bromate ester from the conjugate acid of benzoin, followed by a rapid decomposition of the bromate ester, explains the kinetic data for the oxidation of benzoin.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Wiley InterScience Backfile Collection 1832-2000</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Natarajan, R.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Venkatasubramanian, N.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">International Journal of Chemical Kinetics</subfield><subfield code="d">New York, NY : Wiley</subfield><subfield code="g">8(1976) vom: Feb., Seite 205-214</subfield><subfield code="w">(DE-627)NLEJ159071151</subfield><subfield code="w">(DE-600)1480875-4</subfield><subfield code="x">0538-8066</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:8</subfield><subfield code="g">year:1976</subfield><subfield code="g">month:02</subfield><subfield code="g">pages:205-214</subfield><subfield code="g">extent:10</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://dx.doi.org/10.1002/kin.550080205</subfield><subfield code="q">text/html</subfield><subfield code="z">Deutschlandweit zugänglich</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-WIS</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">8</subfield><subfield code="j">1976</subfield><subfield code="c">2</subfield><subfield code="h">205-214</subfield><subfield code="g">10</subfield></datafield></record></collection>
