amido derivatives of the first‐, second‐, and third‐generation Grubbs ruthenium catalysts were prepared, characterized, and tested in ring‐closing metathesis (RCM) of model dienes. In the ruthenium–amide (formally: 2‐ruthenaindole) form, these complexes exhibit nearly no activity in RCM. However, a dramatic increase of activity was observed upon in situ activation with an ethereal solution of HCl (see
第一代,第二代和第三代Grubbs钌催化剂的空前酰胺衍生物已制备,表征并在模型二烯的闭环复分解(RCM)中进行了测试。在钌-酰胺(原名:2-钌-吲哚)形式下,这些络合物在RCM中几乎没有活性。但是,用HCl的醚溶液原位活化后,观察到活性显着增加(见图)。
