Anwendungen
VerwendenAlternative to other reagents for desulfurizations, dehalogenations(as Wurtz coupling reactions), and Birch reductions.Additionally can be used as: A reducing agent for aliphatic ester substratesA deprotectant in place of the typical heavy metal deprotectant
Darstellung
synthetischeSodium-Potassium Alloy can be prepared by mixing 1 part Sodium and 5 parts Potassium (by weight) in refluxing xylene until melted. The melt is then carefully mixed with a glass stirring rod, keeping the alloy in one large globule. Upon cooling to room temperature, the alloy will remain liquid and can easily be transferred via a glass pipet.[1]
