Second-generation Grubbs’ catalyst and Hoveyda-Grubbs’ catalyst are able to catalyze both crossed [2+2+2] cyclotrimerization of diynes with alkynes and di- or trimerizations of diynes. Selection of the reaction conditions allows us to favor one particular process. The process is selective when applied to unsymmetric diynes.
第二代格拉布斯催化剂和霍韦达-格拉布斯催化剂既能催化二炔与炔烃的交叉[2+2+2]环三聚反应,也能催化二炔的二聚或三聚反应。通过选择反应条件,我们可以选择一种特定的工艺。该过程对不对称二炔具有选择性。
