Summary: The nucleophilic substitution reactions of pentafluoropyridine with hydroxybenzaldehydes were examined, and the selectivity of reactions was found to be influenced by reaction conditions, reactant ratio, and nucleophilicity of the derived potassium formylphenolates. Under mild basic conditions, the nucleophilic attack occurred exclusively at the C-4 position of pentafluoropyridine, resulting in the formation of 4-((perfluoropyridin-yl)oxy)benzaldehydes in high yields. However, under harsh conditions, 3-hydroxybenzaldehyde acted as an effective nucleophile for replacing fluorine atoms at C-2 and/or C-6 positions of pentafluoropyridine. The controlled reactions of pentafluoropyridine with different amounts of 3-hydroxybenzaldehyde led to the synthesis of unsymmetrical products with varying yields.
