Lanthanum, neodymium. and samarium tert-butoxycuprates [(Bu^tO)₅Cu₂Ln]₂ were synthesized in high yields by reactions of Bu^tOCu with lanthanide metals, the halides Sml₂ and LnX₃ (Ln = La, Nd; X = Cl, I) and by the reaction of Bu^tOLi with a mixture of LnCl₃ and CuCl. X-Ray diffraction analysis showed that the structure of [(Bu^tO)₅Cu₂Sm]₂ is based on octahedra formed by four copper atoms in equatorial positions and two samarium atoms in axial positions; the copper and samarium atoms are linked by μ₃-bridging Bu^tO groups. The reactions of lanthanum tert-butoxycuprate with H₂O, HCl, CpH, PhC=CH, and CO₂ were studied.
