through a highly efficient and E-selective C–H activation/Heck/Aza-Wacker sequence. Substoichiometric amounts of benzoquinone can be employed in a cooperative oxidation system with O2, leading to facile purification of products. Modification of the reaction conditions provides a general route to substituted phthalimides by carbonylation with CO. Both systems were found to tolerate a wide range of functionality
提出了一种新的钯(II)催化方法,用于从N-烷氧基苯甲酰胺直接合成亚烷基异吲哚满酮。异吲哚啉酮的形成通过高效的E选择性C–H活化/ Heck / Aza-Wacker序列进行。亚化学计量的苯醌可以与O 2一起在协同氧化系统中使用,从而可以轻松纯化产物。反应条件的改变为通过CO羰基化取代苯二甲酰亚胺提供了一条通用途径。发现这两种体系都可以耐受广泛的功能。
