The reaction of LnCl with NaH in THF at 45 deg C generates the dimeric organolanthanide hydrides, 2 (Ln = Gd, Er, Yb, Lu, Y), in good yield.These new complexes have been fully characterized by elemental analyses, mass spectrometry, IR and NMR spectroscopy.The hydrides can react with alkenes and alkynes.A more active system, organolanthanide hydride/NaH, is able not only to reduce specifically the terminal carbon-carbon double bond but also to catalyse dehalogenation of organic halides.
