Alter ego: In the presence of an appropriate palladium(0) catalyst, carboxylic esters underwent β arylation instead of the more common α‐arylation reaction with aryl halides containing an ortho electronegative substituent (see scheme; Cy=cyclohexyl). An asymmetric version of the reaction gave the product with an enantiomeric ratio of up to 77:23.
自我:在合适的钯(0)催化剂存在下,羧酸酯发生β芳基化反应,而不是与含有邻电负性取代基的芳基卤化物进行更常见的α芳基化反应(参见方案; Cy =环己基)。反应的不对称形式使产物的对映体比例高达77:23。
