been synthesized by several routes, including photocyclization, 3 xenon difluoride intercalate fluorination: and pyrolysis of the diazonium tetrafluoroborate, 5 compounds 2b and 4b had not been described. 6 The present report describes the use of electrolytic fluorination in the presence of fluoride-donating anions (H2F3-of H3F4-) as a means of obtaining the desired fluoro derivatives of 1. The tendency for positive charge localization ...
