Acetylenic alcohols were synthesised from 3-chlor0-4,5~ihydrofuran and its 2-alkyl derivatives, or 5-ch1oro-3,4~ihydro-2Hpyraa and its 6-alkyl derivatives via base catalyzed j3-elimina­tion using sodium metal in THF. Also alkylation followed by hydrolysis of the dilithium salt of w-hydroxy-alk-I-ynes in THF/HMPT leads to the corresponding acetylenic alcohols.
