| Summary: | 碩士 === 國立中興大學 === 化學系所 === 107 === A series of extraordinary nickel and zinc complexes (1)-(7) supported by pentadentate Sciff-base ancillary ligands with various electronic effect of substituents (L1H, L2H, L3H) have been synthesized. These complexes have been structurally characterized by elemental analysis, UV-Vis spectroscopy, as well as NMR studies. X-ray structural studies reveal that znic complexes are ionic composed by a dinuclear cation [LZn2(OAc)2]+ and a variety of anions [Znx(OAc)y]n-. Structures of (5)-(7) show nickel complexes are neutral composed by a dinuclear compound [LNi2(OAc)(SO4)].
Experimental results demonstrate that complexes (1)-(7) show great catalytic activity for the copolymerization of epoxides and carbon dioxide.
