This diamine is a building block for chiral ligands that are useful in asymmetric catalysis.〔Cyrille Kouklovsky, Yves Langlois "(1S,2S)-1,2-Diaminocyclohexane1" in ''Encyclopedia of Reagents for Organic Synthesis'', 2003; John Wiley & Sons. 〕 A mixture of ''cis''- and ''trans''-1,2-diaminocyclohexane is produced by the hydrogenation of ''o''-phenylenediamine. The racemic ''trans'' isomer (mixture of (1''R'',2''R'')-1,2-diaminocyclohexane and (1''S'',2''S'')-1,2-diaminocyclohexane ) can be separated into the two enantiomers using enantiomerically pure tartaric acid as the resolving agent. ==Derived ligands== Representative ligands prepared from (1''R'',2''R'')- or (1''S'',2''S'')-1,2-diaminocyclohexane are diaminocyclohexanetetraacetic acid (CyDTAH4), Trost ligand, and the salen analogue used in the Jacobsen epoxidation. 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「Trans-1,2-Diaminocyclohexane」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.
