Abstract

Alkyl-substituted thiophenes are hydrogenated by the Zn–H2SO4 system to the corresponding 2,5-dihydrothiophenes and thiophanes. In the case of 2-formyl- and 2-acetylthiophene it was established that in substituted thiophenes simultaneous reduction of the substituent to an alkyl group occurs in addition to hydrogenation of the aromatic ring. The optimum conditions for hydrogenation were selected experimentally.
