金属铜催化不对称friedel-crafts alkylation reactions 铜催化不对称Friedel-Crafts烷基化反应是Friedel-Crafts反应的一种特殊形式,在有机合成中扮演了重要的角色。在反应中,铜作为催化剂,能够促进芳族烃或烷基卤化物与芳香族化合物之间发生取代反应,从而实现不对称烷基化。 这种反应可以通过使用手性诱导剂来获得立体异构体...
The Friedel-Crafts Alkylation represents one of the six classes of electrophilic aromatic substitution reactions. The diversity and scope of Friedel-Crafts Alkylations is broad.
What problems can arise during Friedel-Crafts alkylations? Suggest a procedure to get pure n-propyl product and no isopropyl product. Friedel-Crafts reactions increase the number of C-atoms of the reactant. Do you know any other reactions that do this, too? Why does the lab apparatus have ...
