clear, colorless to yellow liquid.
3-Fluoropyridine was used in the synthesis of 3-halopyridin-4-yl-boronic acids and esters.
A combination of CsF and HF provides a very reactive fluoride source and has shown faint promise with 3-chloropyridine giving 3-fluoropyridine in a very low yield.
3-Fluoropyridine is oxidized to corresponding N-oxides, which on treatment with hot acetic anhydride and hydrolysis yields 3-halo-2-pyridones. Microwave spectrum of 3-fluoropyridine has been investigated in the frequency range of 8-18GHz at dry ice temperature. Deprotonation of 3-fluoropyridine with Bu3MgLi in THF at -10°C has been studied.
