Samarium(II) chloride (SmCl2) is achemical compound, used as a radical generating agent in theketone-mediated intraannulation reaction.
Reduction ofsamarium(III) chloride with samarium metal in a vacuum at a temperature of 800 °C to 900 °C, or withhydrogen gas at 350 °C yields samarium(II) chloride:[1]
Samarium(II) chloride can also be prepared by reducing samarium(III) chloride withlithium metal/naphthalene inTHF:[3]
A similar reaction has been observed with sodium.[2]
Samarium(II) chloride adopts thePbCl2 (cotunnite) structure.[2]
The compound co-crystallises withfermium dichloride (FmCl2).[4]
