Abstract
|
|
|
|
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)].
