Abstract

The reactions of 1, 4-dichlorobut-2-yne with HS (CH2) nSH (n= 2–5) or HS (CH2CH2S) nH (n= 2–3) or HSCH2CH (OH) CH2SH under high dilution conditions in industrial methylated spirits using KOH as the deprotonating agent produce thiacycloalkynes in remarkably high yields when the 1: 1 product is a nine-, ten-or 11-membered ring. 1, 5-dithiacyclonon-7-yne, 1, 5-dithiacyclonon-7-yne-3-ol, 1, 6-dithiacyclodec-8-yne, 1, 7-dithiacycloundec-9-yne, 1, ...
