Ferric Chloride, Iron(III) Chloride, Fe(Cl)3
Ferric chloride is a mild oxidizing agent.
Anhydrous FeCl3 oxidizes potassium thiocyanate to the corresponding radical and promotes subsequent addition to nucleophilic olefins to produce dithiocyanate derivatives under mild conditions with excellent yields and chemoselectivities. The use of ferric chloride makes this method simple, convenient and practical.
