The chiral coordination compounds [Co(L)(H2O)2(MeOH)] n (1) and Co2(L)2(H2O)(MeOH)4 (2) were synthesized by the reaction of bis-2,4-[N-(S)-phenylalanyl]6-chlorotriazine (LH2) with cobalt(II) pivalate or acetate. In molecules 2, the CoII ions are linked by a bridging water molecule and two carboxy groups of the L2– anion. By passing the racemate of butan-2-ol through a chromatographic column containing complex 1 as the stationary phase, a mixture enriched with the (S)-isomer of this alcohol can be obtained.
手性配位化合物 [Co(L)(H2O)2(MeOH)] n (1) 和 Co2(L)2(H2O)(MeOH)4 (2) 是通过双-2,4-[N-(S)-苯丙氨酰]6-氯三嗪 (LH2) 与特戊酸钴 (II) 或醋酸钴反应合成的。在分子 2 中,CoII 离子通过桥接水分子和 L2-阴离子的两个羧基相连。将丁-2-醇的外消旋体通过以复合物 1 为固定相的色谱柱,可以得到富含这种醇的(S)-异构体的混合物。
