Abstract
Cobalt 금속 중심으로 cyclopentadienyl을 π-착물로 결합하고, 또 oxime 화합물을 리간드로 하는 cobalt oxime sandwich형 착물을 합성하기 위하여 본 연구를 수행하였다. Cyclopentadienyl-cobalt 부분을 도입하기 위해, (η5-Cyclopentadienyl)bis(ethylene)cobalt (Jonas 시약), (η5-cyclopentadienyl)di(carbonyl)cobalt, 그리고 bis(η5-cyclopentadienyl)cobalt (cobaltocene)의 착물이 사용되었고, oxime을 각각 여러 가지 조건에서 반응시켰다. 그 중에서 Jonas 시약과 dienemonooxime인 2,4-hexadienealdoxime만이 반응되었으며, 그 생성물은 예상을 벗어난 (η5-cyclopentadienyl)(2,4-hexadienenitrile)cobalt [Ⅶ]로 밝혀졌다. 이 화합물의 구조는 NMR, mass spectrometer, IR 원소분석기를 통해 확인되었다.

(η5-Cyclopentadienyl)bis(ethylene)cobalt (Jonas reagent), (η5-cyclopentadienyl)di(carbonyl)cobalt, and bis(η5-cyclopentadienyl)cobalt (cobaltocene) were reacted with oximes, respectively, under various conditions for synthesizing cobalt oxime sandwich complex. Jonas reagent and a dienemonooxime, 2,4-hexadienealdoxime underwent the reaction. This produced unexpected compound, (η5-cyclopentadienyl)(2,4-hexadienenitrile)cobalt [Ⅶ]. The compound [Ⅶ] was identified by NMR, mass spectrometer, IR and elemental analyzer etc.
