measurement of the configurational stability of the stereogenic nitrogen coordinated to M (II) in the corresponding square planar complexes. This stereochemical approach is quite sensitive to steric and electronic effects of the substituents and shown to work well for Ni(II), Pd(II), and Cu(II) complexes. Structural simplicity of the compounds used, coupled with high sensitivity and reliability of experimental
在这里,我们报告了一种通用方法,用于定量测量相应正方形平面络合物中配位至M(II)的立体氮的构型稳定性。这种立体化学方法对取代基的空间和电子效应非常敏感,对Ni(II),Pd(II)和Cu(II)配合物表现出很好的效果。所用化合物的结构简单,再加上实验方法的高灵敏度和可靠性,预示着该方法可用于评估新设计的手性配体的化学稳定性和立体化学性质,以用于定制氨基酸的一般不对称合成。
