Abstract

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, $^13C{^1H}-,\; ^1H-\;and\; ^{19}F-NMR$ spectroscopy and mass spectrometry. The Indium (III) compounds were formed stable 1:1 adducts with acetonitrile. $In(C_6F_5)_3{\cdot}DMAP$ has been prepared from the ligand exchange reaction of In$(C_6F_5)_3 {\cdot} CH_3CN$ with DMAP in $CH_2Cl_2 {\cdot} DMAP$ has higher donating character and replaced the $CH_3CN$ through the ligand transfer reaction.

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$(C_6F_5)_3{\cdot} CH_3CN$과 DMAP(dimethylaminopyridine)를 dichloro methane 용매에서 리간드를 치환반응시켜 In$In(C_6F_5)_3{\cdot}DMAP$를 합성하였다. 리간드들의 치환은 acetonitrile보다 주개 성질이 강한 DMAP가 acetonitrile의 자리에 배위하는 것으로 생각된다.
