The Catellani reaction is a multi-component cascade sequence, catalysed by palladium and norbornene, which typically uses aromatic starting materials. Now, through the use of a modified norbornene co-catalyst, the scope of this reaction has been extended to alkenyl reagents, enabling the preparation of all-carbon tetrasubstituted olefins.

卡泰拉尼的烯基助推剂

Catellani反应是多组分级联序列，由钯和降冰片烯催化，通常使用芳族原料。现在，通过使用改性的降冰片烯助催化剂，该反应的范围已扩展至烯基试剂，从而能够制备全碳四取代烯烃。
