Synthsis and Characterization on Acetonitrile and DMAP Complexes of Indium(III) Compounds

Indium(III)화합물의 Acetonitrile과 DMAP 착물의 합성 및 특성
Zel-Ho Choi

Indium(III) trihalides (halogen=Cl, Br)와 bis(pentafluorophenyl)cadmiumd을 acetonitrile에서 반응시켜 acetonitrile이 배위된 tris(pentafluorophenyl)indium을 합성하였으며 원소분석, 핵자기 공명과 질량분석 스펙트럼을 이용하여 특성을 조사하였다. 그 결과 acetonitrile과 배위한 tris(pentafluorophenyl)indium는 pentafluorophenylindium화합물과 acetonitrile이 1:1로 배위된다는 것을 알 수 있었다. 또한 In(C6F5)3·CH3CN과 DMAP(dimethylaminopyridine)를 dichloro methane 용매에서 리간드를 치환반응시켜 In(C6F5)3·DMAP를 합성하였다.리간드들의 치환은 acetonitrile보다 주개 성질이 강한 DMAP가 acetonitrile의 자리에 배위하는 것으로 생각된다.Tris(pentafluorophenyl)indium acetonitrile complexes have been prepared from the reaction of Indium trihalides (halogen=Cl, Br) and bis(pentafluorophenyl)cadmium in acetonitrile, and characterized by elementary analysis, 13C{1H}-, 1H- and 19F-NMR spectroscopy and mass spectrometry. The Indium (III) compounds were formed stable 1:1 adducts with acetonitrile. In(C6F5)3·DMAP has been prepared from the ligand exchange reaction of In(C6F5)3·CH3CN with DMAP in CH2Cl2. DMAP has higher donating character and replaced the CH3CN through the ligand transfer reaction.
