3,4-Dibromosulfolane (1) was treated with pyridine to form 4-bromo-2-sulfolene (2) by elimination reaction. 4-Bromo-2-sulfolene (2) reacted with substituted benzoic acid salts 3a3c or alizarin yellow (3d) to give four novel allylic substitution products 4a4d by esterification reaction, respectively. These novel compounds 4a4d were determined by IR, 1H NMR, MS spectra and elemental analysis.

Key words: substituted benzoic acid salt, alizarin yellow, esterification, 4-bromo-2-sulfolene, 3,4-dibromosulfolane
