Compounds that have the formula M(NR)(CHR')(OR″)(Pyrrolide), where OR″ is "large" relative to NR and M = Mo or W, have been shown to be Z-selective olefin metathesis catalysts. In this communication we report a new route to Mo complexes in which the relationship between NR and OR″ has been reversed; i.e., the imido ligand is the sterically demanding 2,6-dimesitylphenylimido ligand (NAr*).
通式为 M(NR)(CHR')(OR″)(Pyrrolide) 的化合物，其中 OR″ 相对于 NR 较大，M = Mo 或 W，已被证明是 Z 选择性烯烃复分解催化剂。在本通讯中，我们报告了一种新的 Mo 配合物途径，其中 NR 和 OR″ 之间的关系被颠倒了；即，亚氨基配体是空间位阻较大的 2,6-二甲基苯基亚氨基配体（NAr*）。
