A palladium‐catalyzed, norbornene‐mediated Catellani ortho‐acylation reaction was developed by the use of either acyl chlorides or acid anhydrides as acylation reagents. The addition of more than a stoichiometric amount of H2O is crucial for this transformation when acid chlorides are used, and kinetic studies indicate that the active acylation reagent is possibly an acid anhydride.
通过使用酰氯或酸酐作为酰化剂,开发了钯催化的降冰片烯介导的卡塞拉尼正酰化反应。当使用酰氯时,添加超过化学计算量的H 2 O对于该转化至关重要,动力学研究表明,活性酰化剂可能是酸酐。
