Mercap tides

DR. BRAUMAN I am glad you asked that question. Mercap-tide ions are frequently pictured in organic chemistry as being incredibly reactive and having unusual properties. However, our experimental results indicate that they fit exactly on the plot which I showed. Thus, in the gas phase, their behavior appears normal. 

Reactive substrates are those with a good leaving group, such as halide (in acyl halides), hydrosulfide (in thioadds), alkyl thiolate or alkyl mercap-tide (in thioesters), and carboxylate (in anhydrides). 

Air sweetening a process in which air or oxygen is used to oxidize lead mercap-tides to disulfides instead of using elemental sulfur.

Caution. The syntheses described below should be carried out in a well-ventilated hood because of the release of CO and the strong stench of mercap-tides. Schlenk-type glassware should be used for most procedures. 

The product obtained in this reaction indicates that terminal mercap-tide groups are much better nucleophiles than bridged groups (34). 

Sulfides. Symmetrical sulfides can be prepared in high yield from the reaction of alkyl halides and sodium sulfide in water with this phase-transfer catalyst. Unsymmetrical sulfides are prepared from alkyl halides and sodium mercap-tides. Secondary alkyl halides react more slowly than primary halides bromides are more reactive than chlorides. ...

Newcomers are antimony-based stabilizers. The interest for these compounds is due to the classification, in the United States, of antimony mercap-tide as a nontoxic chemical [39].
