When subjected to arylboranes, anionic trifluoromethyl and difluorobenzyl palladium(II) complexes undergo fluoride abstraction followed by 1,1-migratory insertion. The resulting intermediate fluoroalkyl species can be induced to undergo a subsequent transmetalation and reductive elimination from either an in situ formed fluoroboronate (FB(Ar3)-) or an exogenous boronic acid/ester (ArB(OR)2) and nucleophilic activator, representing a net defluorinative arylation reaction. The latter method enabled a structurally diverse substrate scope to be prepared from either an isolated palladium-CF3 complex, or from Pd(PPh3)4 and other commercially available reagents.

Pd(II)氟烷基配合物的脱氟功能化

当受到芳基硼烷时，阴离子三氟甲基和二氟苄基钯 (II) 配合物会发生氟化物提取，然后是 1,1-迁移插入。可以诱导所得中间体氟烷基物质进行随后的金属转移和还原消除，从原位形成的氟硼酸盐 (FB(Ar3)-) 或外源性硼酸/酯 (ArB(OR)2) 和亲核活化剂，代表净脱氟芳基化反应。后一种方法能够从分离的钯-CF3 复合物或 Pd(PPh3)4 和其他市售试剂制备结构多样化的底物范围。
