Abstract
Dimethyl thiophene-2,5-dicarboxylate(1) was prepared by esterification of thiophene-2,5-dicarboxylic acid and methanol in the presence of chlorate sulfoxide.Thiophene-2,5-dicarbohydrazide(2) was obtained by reaction of 1 and hydrazine.A novel amphiphilic molecule(3),thiophene gemini surfactant with Schiff base,was synthesized by condensation reaction of 2 and octan-2-one.The structures of 2 and 3 were confirmed by ~1H NMR,IR and elemental analysis.
