Carbon dioxide-mediated metal-free oxidation of allylic alcohols to esters

Carbon dioxide-mediated metal-free oxidation of allylic alcohols to esters

This study shows that CO sub(2) can be used as a mild oxidant under metal-free and relatively mild conditions. Various allylic alcohols are oxidized to esters by the CO sub(2)-mediated oxidation, followed by N-heterocyclic-carbene-catalyzed esterification. The reduced CO sub(2) was observed as formi...

Zusammenfassung:This study shows that CO sub(2) can be used as a mild oxidant under metal-free and relatively mild conditions. Various allylic alcohols are oxidized to esters by the CO sub(2)-mediated oxidation, followed by N-heterocyclic-carbene-catalyzed esterification. The reduced CO sub(2) was observed as formic acid by LC-MS analysis.
