Abstract
Schiff 리간드인 (Z)-N-((Z)-2-(sec-butylimino)-1,2-diphenylethylidene)butan-2-amine을 벤질과 sec-부틸아민과의 축합반응에 의해 합성하였다. 일 주기 전이금속인 망간(II) 및 니켈(II)과 리간드와의 착물반응을 시도하였다. 리간드 및 착물의 특성을 FTIR, 원소분석 및 열무게분석으로 고체 상태에서, 그리고 NMR(1H, 13C)로 용액 상태에서의 각각 조사하였다. 두 착물 모두 온화한 조건에서 methylaluminoxane (MAO) 존재 하에 부타디엔 올리고화 반응의 조촉매로 좋은 촉매활성을 보였다.

A Schiff base ligand (Z)-N-((Z)-2-(sec-butylimino)-1,2-diphenylethylidene)butan-2-amine was synthesized by condensation of benzil with sec-butyl amine. Complexation of the ligand was carried out with first row transition elements, manganese(II) and nickel(II). Ligand and complexes were characterized by FTIR, elemental analysis and thermogravimetric analysis in solid state and by NMR (1H, 13C) in solution form. Both the complexes demonstrate good catalytic activity for butadiene oligomerization under mild conditions with methylaluminoxane (MAO) as co-catalyst.
