Useful:

• Canonical SMILES: CC(=O)S.[K+]
• Uses: Potassium Thioacetate is the potassium salt of Thioacetic Acid, a commonly used reagent in organic synthesis for the introduction of thiol groups in molecules. Potassium thioacetate is used for palladium mediated coupling with aryl halides and triflates leading to S-arylthioacetates and derivatives. It is also used as a reagent in the conversion of halides to thiols.
