Used as a selective reducing agent in organic synthesis, particularly for the reduction of alkyl halides and epoxides. It offers mild reaction conditions and high chemoselectivity, making it valuable in complex molecule synthesis where functional group compatibility is crucial. Also employed in radical-mediated reactions, facilitating carbon-carbon bond formation. Its utility extends to polymer chemistry, where it acts as a chain transfer agent in controlled radical polymerization, helping regulate molecular weight and polydispersity.
