    摘要:
    A versatile, monoanionic, chelating (bis)carbene ligand (2) was used to prepare a thorium dihalide complex (3) and a direduced-bpy derivative (4).: CASSCF calculations suggest the involvement :of a multiconfigurational open-shell singlet, with the main configuration corresponding to a Th(III), bpy(-1) (f(1)pi*(1)) electronic structure. The reactivity of 4 was explored in. various transformations, including reactions with carbonyls and organic azides; the latter gave rise to an unusual terminal Th-imido bpy complex (6).

    [H2B(MesIm)2]Nb(NtBu)Me2 (3) bearing a bis(NHC)borate (NHC = N-heterocyclic carbene) supporting ligand are described. The reaction of the dimethyl complex (3) with excess CO generates an equivalent of acetone, which inserts into a B–H bond of the bis(NHC)borate ligand to form a boryl isopropoxide/niobium(III) dicarbonyl complex (4). This mode of hydroboration reactivity also occurs readily upon the treatment

The catalysts feature unusual stability, particularly for a base metal catalyst, enabling >1.1 million turnovers of CO2. Moreover, while other systems involve more expensive reducing reagents, sodium borohydride is inexpensive and easily handled. Furthermore, effecting reduction in the presence of water enables

    Neutral pi-allylpalladium(II) carbene complexes, [H2B(ImR)(2)]Pd(pi-allyl) (H2B(ImR)(2) = bis(3-alkylimidazol-2-ylidene)borate, R = Mes, 1a; Cy, 1b; Bu-t, 1c), and their B-H fluorinated derivatives have been synthesized and characterized by H-1, C-13 and F-19 NMR, along with X-ray crystal structural determination for 1a and 1c. The results reveal that the Pd(II) ion is in a distorted square planar environment in 1a and 1c, and is coordinated by one allyl ligand and one bis(3-alkylimidazol-2-ylidene)borate ligand.
