As a further test of the concept of regioexhaustivefunctionalization, 2-chloro-6-(trifluoromethyl)pyridine, 2-chloro-5-(trifluoromethyl)pyridine and 3-chloro-4-(trifluoromethyl)pyridine were each converted into the three possible carboxylic acids. This was achieved by employing several, but not all of the organometallic qtoolbox methodsq; transformation of a more basic organometallic species into
