Cobalt(ii)-catalyzed oxidative esterification of aldehydes: a cooperative effect between cobalt and iodide ions
Literature Information
Ya-Fei Guo, Bao-Hua Xu, Ting Li, Lei Wang, Suo-Jiang Zhang
The efficient cobalt(II) catalyzed oxidative alkoxylation of aldehydes, a method directly leading to the corresponding esters, is presented. Mechanism studies provide extensive insights into the cobalt mediated decomposition of TBHP in the presence of the iodide ion. The in situ generated hypoiodites (IOβ/IO2β) mainly from conversion of I3β to IO3β account for a cooperative effect with the oxygen centered radical species to make the important hydrogen abstraction of hemiacetal intermediates more selective, thereby offering high efficiency.
