Reductive Catalytic Difluorocarbene Transfer via Palladium Catalysis.
Zhang XY, Sun SP, Sang YQ, Xue XS, Min QQ, Zhang X. Zhang XY, et al. Angew Chem Int Ed Engl. 2023 Sep 11;62(37):e202306501. doi: 10.1002/anie.202306501. Epub 2023 Aug 3. Angew Chem Int Ed Engl. 2023. PMID: 37365143
Experimental mechanistic studies reveal that an unexpected Pd(0/II) catalytic cycle is involved in this reductive reaction, wherein the oxidative addition of palladium(0) difluorocarbene ([Pd(0) (L(n) )]=CF(2) ) with aryl electrophile to generate the key intermediate aryld …

Nickel-Catalyzed Difluoroalkylation of β,γ-Unsaturated α-Amino Nitrile Derived Lithium Reagents.
Tong FF, Luo YC, Zhao HY, Fu XP, Zhang X. Tong FF, et al. Angew Chem Int Ed Engl. 2024 Nov 20:e202417858. doi: 10.1002/anie.202417858. Online ahead of print. Angew Chem Int Ed Engl. 2024. PMID: 39564815
This approach allows for the efficient and precise construction of secondary C(sp(3))-CF(2)R bonds, previously challenging in transition-metal-catalyzed fluoroalkylation reactions due to beta-hydride elimination. ...
