Abstract |
디포스핀을 포함한 몇가지 d8 전이금속착물(MCl2PP)은 출발물질 KnMClm을 사용하여 합성하였다. 중심금속(M)은 Ni(Ⅱ), Pd(Ⅱ), Pt(Ⅱ), Au(Ⅲ)이며, 디포스핀(PP)은 bis(diphenylphosphino)methane(dppm), bis(diphenylphosphino)ethane(dppe), bis(diphenylphosphino)propane (dppp) 및 bis(diphenylphosphino)ethylene(dppety)이었다. 착물의 조성이나 특성은 원소분석과 1H-NMR, 31P-NMR 및 UV-Visible 스펙트럼을 이용하여 확인하였다. 이들 착물의 촉매적 활성은 3(2H)-furanone 및 cyclic carbonate 생성반응에 대하여 각각 조사하였다. 2-methyl-3-butyn-2-ol로부터 생성물 3(2H)-furanone을 얻은 반응 (1)에서 Ni(Ⅱ)-, Pd(Ⅱ)-diphosphine 착물은 좋은 촉매적 효과를 나타내었다. 그러나 이들 diphosphine 착물들은 cyclic carbonate 생성반응 (2)에 대해 촉매제로서의 활성을 거의 나타내지 않았다. The d8-transition metal complexes containing diphosphine, MCl2PP were prepared by using KnMClm as starting materials, wherein M were Ni(Ⅱ), Pd(Ⅱ), Pt(Ⅱ) and Au(Ⅲ) and PP were bis(diphenylphosphino)methane(dppm), bis(diphenylphosphino)ethane(dppe), bis(diphenylphosphino)propane (dppp) and bis(diphenylphosphino)ethylene(dppety). The complexes were characterized by the spectral property (1H-NMR, 31P-NMR and UV-Visible spectra) together with elemental analysis. The complexes were tested for the catalytic activity on the formation reactions of 3(2H)-furanone and cyclic carbonate. The only Ni(Ⅱ)- and Pd(Ⅱ)-diphosphine complexes displayed a good catalytic effects in the production of 3(2H)-furanone from 2-methyl-3-butyn-2-ol [reaction (1)]. But all the diphosphine complexes as catalyst were almost inactive towards cyclic carbonate production preaction [reaction (2)]. |
