Highly substituted alkenylsilanols (1), readily prepared from commercially available simple starting materials, are efficiently coupled with aryl or alkenyl halides in the presence of tetrabutylammonium fluoride (TBAF) and a palladium(0) catalyst. Yields are generally high and the reactions are highly stereoselective and compatible with a wide range of functional groups.
由市售简单原料容易制备的高度取代的烯基硅烷醇(1)在氟化四丁基铵(TBAF)和钯(0)催化剂存在下与芳基或烯基卤化物有效偶联。收率通常很高,并且反应是高度立体选择性的,并且与多种官能团相容。
