imidoyl palladium migration, followed by intramolecular arylation. The fluoren-9-one synthesis appears to involve both a palladium migration mechanism and a C-H activation process proceeding through an unprecedented organopalladium(IV) hydride intermediate. The results from deuterium labeling experiments are consistent with the proposed dual mechanism.
具有生物学意义的 fluoren-9-one 和 xanthen-9-one 衍生物已通过新型芳基到亚胺酰基钯的迁移,然后进行分子内芳基化制备。芴 9-one 合成似乎涉及钯迁移机制和 CH 活化过程,该过程通过前所未有的有机钯 (IV) 氢化物中间体进行。氘标记实验的结果与提出的双重机制一致。
