3-(4-Methylpent-3-enyl)thiophene → HCID 13220121, compound

Participants

Reaction Steps

To 12 g of freshly distilled 3-(4-methyl-pent-3-enyl)-thiophene dissolved in 150 ml ethanol was added 1 g of 5% Pd/C hydrogenation catalyst. The mixture was hydrogenated at atmospheric pressure in 72 hours. The catalyst was filtered of, the solvent evaporated and the residue distilled, yielding 8 g (66%) 3-(4-methylpentyl)-thiophene. Boiling point: 65°-66° C./0.13 kPa. nD20 =1.4962.
