Abstract
The oxidation of formic and oxalic acids by benzyltrimethylammonium dichlor oiodate (BTMACI), in the presence of zinc chloride, leads to the formation of carbon dioxide. The reaction is first order with respect to BTMACI, zinc chloride and organic acid. Oxidation of deuteriated formic acid indicates the presence of a kinetic isotope effect. Addition of benzyltrimethylammoni um chloride enhances the rate. It is proposed that the reactive oxidizing s pecies is [(PhCH2Me3N)(+) (IZn2Cl6)(-)]. Suitable mechanisms have been prop osed.
