Phenyl selenocyanate is a chemical compound that functions as a reagent in organic synthesis. It acts as a source of the selenocyanate anion, which can various reactions to introduce the selenocyanate functional group into organic molecules. Phenyl Selenocyanate participates in nucleophilic substitution reactions, where the selenocyanate anion replaces a leaving group in the substrate molecule. This substitution reaction allows for the formation of new carbon-selenium bonds. The mechanism of action of phenyl selenocyanate involves its interaction with the substrate molecule, leading to the formation of the desired carbon-selenium bond.
