Optically active (1R,2S)-1-aminomethyl-2-methylcyclohexylamine (R,S-2m-amcha) was synthesized and two Pt(II) and two types of Co(III) complexes containing this ligand were prepared. 1H-NMR and 13C-NMR spectra of the Pt(II) complexes and CD spectrum of trans-[CoCl2(R,S-2m-amcha)2]+ indicated that the chelate ring takes predominantly the λ conformation with the equatorial C1–C2 bond of the cyclohexane
合成了具有光学活性的 (1R,2S)-1-氨基甲基-2-甲基环己胺 (R,S-2m-amcha) 并制备了两种 Pt(II) 和两种类型的含有该配体的 Co(III) 配合物。Pt(II) 配合物的 1H-NMR 和 13C-NMR 光谱和反式-[CoCl2(R,S-2m-amcha)2]+ 的 CD 光谱表明螯合环主要采用 λ 构象与赤道 C1–环己烷环的 C2 键。配体的绝对构型是根据复合物的构象确定的。tris Co(III) 复合物的所有可能异构体 fac-Δ(lel3)、mer-Δ(lel3)、mer-Λ(ob3) 和 fac-Λ(ob3) 都被分离和表征。
