Catalyzed Oxidation

Cobalt(II) chloride catalyzed oxidation of 2-substituted 1,3-dioxolanes in 1,2-dimethoxyethane afforded formate esters and acids in high yields. It was found that the presence of catalytic amounts of ZnCl2 increased the rate of oxidation. A free-radical mechanism is proposed, involving participation of superoxocobalt, and the esterification of the alcohol and acid.

Free Radical Mechanism

Unlike C-N bond formation with classical dirhodium(II)-nitrenoids as the key intermediate, dirhodium(II)-catalyzed 1,2-and 1,3-diamination reactions are realized by a free radical mechanism. A mechanistic study revealed that the reactions undergo...
