Synthesis and some properties of lanthanum, neodymium, and samarium tert-butoxycuprates [(Bu(t)O)(5)Cu(2)Ln](2)

Lanthanum, neodymium, and samarium tert-butoxycuprates [((BuO)-O-t)(5)Cu(2) Ln](2) were synthesized in high yields by reactions of (BuOCu)-O-t with lan thanide metals, the halides SmI2 and LnX(3) (Ln = La, Nd: X = CI, I) and by the reaction of (BuOLi)-O-t with a mixture of LnCl(3) and CuCl. X-Ray diff raction analysis showed that the structure of [((BuO)-O-t)(5)Cu2Sm]2 is bas ed on octahedra formed by four copper atoms in equatorial positions and two samarium atoms in axial positions; the copper and samarium atoms are linke d by mu(3)-bridging (BuO)-O-t groups. The reactions of lanthanum tert-butox ycuprate with H2O, HCl, CpH. PhC drop CH, and CO2 were studied.
