1,2-Ethanedithiol
1,2-Ethanedithiol is an odorous, colorless liquid with the formula C2H4(SH)2. It is a common building block in organic synthesis and an excellent ligand for metal ions. Additional recommended knowledgeApplications in organic chemistryIt is widely used in organic chemistry because it reacts with aldehydes and ketones to give 1,3-dithiolanes, which are useful intermediates. [1]
Other 1,2- and 1,3-dithiols undergo this reaction to give related 1,3-dithiolanes and 1,3-dithianes (six-membered rings). Diols such as ethylene glycol undergo analogous reactions to 1,3-dioxalanes and 1,3-dioxanes. One distinguishing feature of the dithiolanes and dithianes derived from aldehydes is that the methyne group can be deprotonated and the resulting carbanion alkylated. SynthesisIt can be prepared by the action of 1,2-dibromoethane on thiourea followed by hydrolysis.[2] References
