摘要: Divalent and solvent-free: the ytterbium hydrido complex 1 was obtained by hydrogenolysis of [(Tp(tBu,Me))Yb(CH(2)SiMe(3))(thf)]. The steric demand bulky hydrotris(3-tert-butyl-5-methylpyrazolyl)borate ligand, Tp(tBu,Me), is sufficient to stabilize dimer, yet facile room-temperature reactions with amines, alkynes, diynes, CO indicate a rich chemistry 1.
