The synthetic potential of 3,4-dibromofuran has been assessed by its conversion into 3,4-disubstituted furans via mono-S-ipso-substitution. The ability of 3-methylthio and 3-phanylthio substituents for directing the metallation at position ct-rclative to the substitucnt has allowed the regiospccific
