additives in the reaction of self-dimerization of alkoxychromium(0) (Fischer) carbenecomplexes resulted in the selection of Pd(PtBu3)2 to effect this transformation with good to excellent E selectivities and acceptable to excellent chemical yields. This catalyst will allow the control of the geometry in the synthesis of polyconjugated olefins, one emerging application of these catalytic reactions.
对烷氧基铬(0)(Fischer)卡宾配合物自二聚反应中不同催化剂和添加剂的影响进行系统研究后,选择了Pd(P t Bu 3)2来实现具有良好或优异E的转化。选择性和优良的化学收率是可以接受的。该催化剂将允许控制聚共轭烯烃的合成中的几何形状,这些催化反应的一种新兴应用。
