摘要

Abstract In accordance with the concept of regioexhaustive functionalization, both 3-chloro-2- (trifluoromethyl) pyridine and 2-bromo-6-(trifluoromethyl) pyridine were converted each time into the three possible carboxylic acids (1, 4 and 5 and 6, 9 and 12, respectively). 2-Bromo-4- (trifluoromethyl) pyridine, 2-bromo-5-(trifluoromethyl) pyridine, 2-iodo-4-(trifluoromethyl) pyridine and 4-iodo-2-(trifluoromethyl) pyridine were selectively deprotonated and ...
