The reaction between low-valent tin hydride and trivalent rare-earth-metallocene alkyls yielded specific complexes, while the addition of low-valent lead compounds to rare-earth-metal hydrides also produced lead complexes, which exhibit H/D exchange under specific conditions.
Following the alkane-elimination route, the reaction between tetravalent aryl tintrihydride Ar*SnH3 and trivalent rare-earth-metallocene alkyls [Cp*(2)Ln(CH{SiMe3}(2))] gave complexes [Cp*(2)Ln(mu-H)(2)SnAr*] implementing a low-valent tin hydride (Ln=Y, Lu; Ar*=2,6-Trip(2)C(6)H(3), Trip=2,4,6-triisopropylphenyl). The homologous complexes of germanium and lead, [Cp*(2)Ln(mu-H)(2)EAr*] (E = Ge, Pb), were accessed via addition of low-valent [(Ar*EH)(2)] to the rare-earth-metal hydrides [(Cp*(2)LnH)(2)]. The lead compounds [Cp*(2)Ln(mu-H)(2)PbAr*] exhibit H/D exchange in reactions with deuterated solvents or dihydrogen.
