The palladium-catalysed aminocarbonylation of 2-iodobornene and 3-iodo-2-quinuclidene, possessing iodo alkene functionality, resulted in the high-yielding synthesis of the corresponding carboxamide derivatives. The substrates were synthesised from camphor and 3-quinuclidone, respectively, via their hydrazones. The chemoselective homogeneous carbonylation reaction of synthetic value was carried out under mild reaction conditions. While the carbonylation of the 2- iodobornene was found to be a facile reaction with yields of synthetic interest, its isomer, 1-iodocamphene, formed in Wagner-Meervein rearrangement, remained intact under the same reaction conditions.
以铂催化的2-碘薄荷烯和3-碘-2-喹诺克利丁的氨基羰基化反应,具有碘烯烃功能团,结果高产率合成了相应的羧酰胺衍生物。这些底物分别通过其肼基衍生物从樟脑和3-喹诺克酮合成。具有合成价值的选择性均相羰基化反应在温和的反应条件下进行。尽管2-碘薄荷烯的羰基化反应被发现较为简单且产率具有合成意义,但其异构体1-碘薄荷烯在瓦格纳-梅尔弗朗重排中形成,在相同反应条件下保持不变。
