experimental conditions have been developed for an efficient catalytic Pauson–Khand reaction. These are based on the use of a mixture of molecular sieves and tert-butanol as inducers of the process. This mixture, with the appearance of a paste, is able to adsorb CO, thus improving the conversion and making it possible to effect the reactions in the absence of a CO atmosphere. The protocol is applied
为有效的Pauson-Khand催化反应开发了新的实验条件。这些基于使用分子筛和叔丁醇的混合物作为该方法的诱导剂。该混合物具有糊状外观,能够吸附CO,因此提高了转化率,并且使得可以在没有CO气氛的情况下进行反应。该方案应用于已知和未知的底物,并与先前描述的条件进行了比较,在分子内和分子间实例中均显示出良好的结果。
