Treatment of (E)-4,4,4-trifluoro-1-aryl-2-buten-1-one with various aryldiazonium salts in the presence of palladium catalyst gave the corresponding α-arylated Heck adducts with high regio- and stereoselectivity in good to high yields.
在
钯催化剂存在下,用各种芳基重氮盐处理(E)-4,4,4,4-三
氟-1-芳基-
2-丁烯-1-酮,得到相应的α-芳基化Heck加合物,具有较高的区域选择性和立体选择性。好到高产。
