Caught in a pincer: A chiral, imidazolidine‐derived NCN‐type palladium pincer complex has been prepared using a ligand introduction technique. Single‐crystal X‐ray diffraction analysis of this complex showed a well‐organized asymmetric sphere. The neutral palladium/chloride version exhibited significant catalytic activity for the reaction of nitroalkenes with malononitrile to give products in a highly
陷入困境:使用配体引入技术制备了手性咪唑烷衍生的NCN型钯夹子复合物。该复合物的单晶X射线衍射分析显示组织良好的不对称球体。中性钯/氯化物形式对硝基烯烃与丙二腈的反应显示出显着的催化活性,从而以高对映选择性的方式提供产物(参见方案)。
