Relevant oxidation states are Sb(V) and Sb(III). The toxicity of antimony limits practical application in organic chemistry.〔C. Elschenbroich, A. Salzer ''Organometallics : A Concise Introduction'' (2nd Ed) (1992) from Wiley-VCH: Weinheim. ISBN 3-527-28165-7〕 ==Organoantimony(V) chemistry== Antimony compounds of the type R5Sb (stiboranes) can be synthesised from trivalent Sb precursors: :Ph3Sb + Cl2 → Ph3SbCl2 :Ph3SbCl2 + 2 PhLi → Ph5Sb Asymmetric compounds can also be obtained through the stibonium ion: :R5Sb + X2 → ()+() :()+() + R'MgX → R4R'Sb Just as in the related organobismuth compounds (same group 15), organoantimony(V) compounds form onium compounds and ate complexes. Pentaphenylantimony decomposes at 200 °C to triphenylstibine and biphenyl. It forms a trigonal bipyramidal molecular geometry. In the related Me5Sb all methyl protons are equivalent at -100 °C in proton NMR. Compounds of the type R4SbX tend to form dimers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Organoantimony chemistry」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
