ambiphilic, N-boryl imine ligands, wherein boron is associated with a Lewis basic imine nitrogen. These ligands can be easily generated in two steps from the corresponding pyridinyl- and phosphinyl-tethered aldehydes. 11B NMR analysis suggests the association of the Lewis acidic boron to either the pyridine unit or via intermolecular acid/base interactions with the imine. Both of these ligands can coordinate
我们在这里描述了两类新的两亲性N-硼基亚胺配体的合成和结构表征,其中硼与路易斯碱性亚胺氮相关。这些配体可以很容易地在两个步骤中由相应的吡啶基和次膦基连接的醛生成。11 B NMR分析表明路易斯酸性硼与吡啶单元或通过与亚胺的分子间酸/碱相互作用而缔合。这两个配体都可以与钯配位,并且通过X射线晶体学证实了它们的结构。
