An enantiomerically pure Mo-based complex that bears an alkylimido ligand is prepared and characterized through NMR spectroscopy and X-ray analysis. Mo complex 4 is the only reported chiral alkylimido catalyst; all previous chiral complexes are arylimido systems. These studies show that the chiral Mo catalyst exists exclusively as the syn isomer and that it offers unique reactivity and selectivity
制备了带有烷基亚氨基配体的对映异构纯 Mo 基复合物,并通过 NMR 光谱和 X 射线分析对其进行表征。Mo配合物4是唯一报道的手性烷基亚氨基催化剂;所有以前的手性配合物都是芳基亚氨基体系。这些研究表明,手性 Mo 催化剂仅作为顺式异构体存在,并且它在不对称烯烃复分解中提供了独特的反应性和选择性。
