Norbornenone (5b), obtained from the reaction of 2,5-dimethyl-3,4-diphenylcyclopentadienone dimer (3) with bromomaleic anhydride (4b), provides an excellent base-triggered source of carbon monoxide for palladium-catalysed carbonylation reactions. Aminocarbonylation, ketoamide synthesis, and Suzuki–Miyaura reactions of aryl iodides carried out in a two-chamber reaction vessel gave good to excellent yields of
由 2,5-二甲基-3,4-二苯基环戊二烯酮二聚体 ( 3 ) 与溴马来酸酐 ( 4b ) 反应获得的降冰片烯酮 ( 5b )为钯催化的羰基化反应提供了极好的碱触发一氧化碳源。在两室反应容器中进行的芳基碘化物的氨基羰基化、酮酰胺合成和 Suzuki-Miyaura 反应产生了良好的羰基化产物产率。
