Nitrogen-containing compounds have been subjected to electrochemical oxidation with Et3N-3HF as an electrolyte. Caffeine afforded 8- fluorocaffeine as a sole product in 40.3% yield. Guanosine tetraacetate and uridine triacetate gave the fluorinated compounds in 17.5 and 4.6% yields, respectively. Similar electrochemical oxidation of caffeine with methanol, KCl, or KCN afforded 8-methoxycaffeine, 8-chlorocaffeine, or 8- cyanocaffeine, respectively.
