According to Sams et al, "Molecular Sieve Fluorination of Fluorobenzene Using Elemental Fluorine," J. Org. Chem. 43(11), 2273 (1978), attempts were made to prepare 1,3-difluorobenzene using a molecular sieve fluorination technique. Fluorination of monofluorobenzene resulted in the isolation of various isomers of difluorobenzene in 19% yield; the highest reported yield for the meta isomer was 1.2%.
