A catalyst, rhenium heptasulfide, has been found for reducing 2-thiophenaldehyde and 2-acetylthiophene to the corresponding alkylthiophenes. The reduction conditions found were: temperature 170° -190° C, hydrogen pressure 130 atm, time 3–6 hr. Reduction of 2-thiophenaldehyde in methanol in the presence of rhenium heptasulfide gives 2-methoxythiphene, while corresponding hydrogenation of 2-acetylthiophene in ammonia plus dioxane gives 2-(α -aminoethyl) thiophene.
