9. -3) as supporting electrolyte. The cathode was a glassy carbon electrode and the anode a platinum wire. The reference electrode was a saturated calomel electrode. The cell was charged with 0.5 mmol of aryl iodide, 10 mol-% of the catalyst and 2 equivalents of formic acid. Electrolyses were performed at constant potential (see Table 1) under one atmosphere of CO at 60°C. After acidic hydrolysis, the mixture was extracted with diethyl ether. Crude reaction mixtures were then analyzed by GC analysis and yields were calculated by using authentic samples as external standards.
