Abstract:3-Bromothiophene and 3,4-dibromothiophene were synthesized in high yields from thiophene, 48% (m/m) aqueous hydrobromic acid, 35% (m/m) aqueous hydrogen peroxide solution, anhydrous liquid ammonia and sodium. In the presence of (dppp)NiCl 2, 3-bromothiophene and 3,4-dibromothiophene reacted with Grignard reagents to afford 3-alkylthiophene and 3,4-dialkylthiophene in good yields, respectively. 3-Alkoxythiophene was synthesized from 3-bromothiophene and alcohol using CuI and anhydrous sodium bisulfate as catalysts. The compounds obtained were characterized by 1H NMR, MS spectra and elemental analysis.
Keywords:thiophene derivative  synthesis  characterization
