The base-catalyzed reactions of p 4luorobenzoyl chloride provkle a convenient method for 'OF NMR analysls of alcohols, phenols, carboxylic acids, amlnes, and thiols. The'OF chemlcal shlft and yleld data for p-fluorobenzoyl derlvatives for nearly 100 compounds are presented. The yield data for these p-fluorobenroyi derlvatlves suggest a slmple, and In many cases, quantltatlve method for Introducing a fluorine tagglng group. The 'OF ...
