摘要

摘要在钯催化下，五氟苯基三氟硼酸钾与芳基氯化物在 SIMes 碳烯前体存在下发生交叉偶联反应时，五氟联苯的产率降低，而在相同条件下从 4-溴甲苯中生成 2,3,4,5,6-五氟-4'-甲基联苯的产率增加。对这一现象以及初始硼酸盐的副氢化反应加剧提出了解释。

Unexpected Effect of N-Heterocyclic Carbene on the Catalytic Activity of Palladium Complex in the Cross-Coupling Reaction of K[C6F5BF3] with Aryl Chlorides

In the palladium-catalyzed cross-coupling of potassium pentafluorophenyltrifluoroborate with aryl chlorides in the presence of the precursor of SIMes carbene, the yields of pentafluorobiphenyls decrease, whereas the yield of 2,3,4,5,6-pentafluoro-4'-methylbiphenyl from 4-bromotoluene under the same conditions increases. An explanation for this phenomenon and for the intensification of the side hydrodeboration reaction of the initial borate has been proposed.
