and kinetic inertness. To circumvent these problems, a simple reaction system is reported comprising ammonium carbamates as carbon dioxide surrogates, propargylicalcohols, and a silver(I) catalyst, for the effective conversion of a wide range of alcohols and secondary amines into the corresponding β‐oxopropylcarbamates. A key feature of this strategy includes quantitative use of a carbon resource with

Two nickel(II) complexes, [Ni(acac)(2)(dmpeO(2))](n) .2CHCl(3) (1) and [(Ni(acac)(MeO)(MeOH)](4) (2) (acac = pentane-2,4-dionato) have been synthesized and characterized by elemental analysis, FT-IR spectroscopy, and single crystal X-ray diffraction. The geometries around the central nickel(II) ion are distorted octahedral in both complexes. The equatorial plane includes four oxygen donor atoms of two acetylacetonato ligands and the axial positions are occupied by two oxygen atoms of two dmpeO2 ligands. Complex 1 has a polymeric chain structure in the solid state, while complex 2 has a tetranuclear cubane structure. These complexes are the first reported examples of polymeric and tetranuclear structures of Ni((II) containing acac-ligand. Neither complex is catalytically active for the hydrogenation of CO2 to formamide, even though a mixture of Ni(acac)(2) and dmpe form a very active in situ catalyst together. (C) 2017 Elsevier B.V.
