Syntheses of substituted pyridines and fluorinated compounds, which are often pharmaceutical targets, are important objectives in organic chemistry. Herein, we found that decarboxylative fluorination of lithium 2‐pyridylacetates occur under catalyst‐free conditions. The phenomenon can be applied to one‐pot transformation of substitutedmethyl 2‐pyridylacetate to 2‐(fluoroalkyl)pyridine by decarboxylative
