- Palladium and Nickel Catalyzed Suzuki Cross-Coupling with Alkyl Fluorides
-
Suzuki cross-coupling of benzylic and unactivated aliphatic fluorides with aryl- and alkenylboronic acids has been achieved via mechanistically distinct Pd and Ni catalyzed pathways that outperform competing protodeboronation, β-hydride elimination, and h

- Dual copper- and photoredox-catalysed C(sp2)-C(sp3) coupling
-
The use of copper catalysis with visible light photoredox catalysis in a cooperative fashion has recently emerged as a versatile means of developing new C-C bond forming reactions. In this work, dual copper and photoredox catalysis is exploited to effect C(sp2)-C(sp3) cross-couplings between aryl boronic acids and benzyl bromides.

- Preparation of functionalized organoindium reagents by means of magnesium insertion into organic halides in the presence of InCl3 at room temperature
-
Magnesium, indium, palladium: An efficient one-pot procedure for the direct preparation of triorganoindium reagents from organic halides by means of magnesium insertion in the presence of InCl3 and LiCl is reported (see scheme). The organoindium reagents are obtained in good yields from functionalized aryl, heteroaryl, and alkyl bromides and benzyl chlorides at 25 °C in THF within 4h. Moreover, the resulting organoindium reagents could be efficiently used as reagents in Pd-catalyzed cross-coupling reactions with a wide functional group tolerance. Copyright

- Preparation process of fluorine substituted aromatic compound
-
A preparation process of a fluorine substituted aromatic compound comprising reacting an alkali metal or alkali earth metal salt of an aromatic compound having a hydroxy group with an organic fluorinating agent is disclosed. As a representative fluorinating agent, a bis-dialkylamino-difluoromethane compound, for example, 2,2′-difluoro-1,3-dimethylimidazolidine, is exemplified. According to the process, an industrially useful fluorinated aromatic compound, for example, a fluorobenzene, a fluorine substituted benzophenone, a fluorine substituted diarylsulfone can be prepared with ease in economy without specific equipment.
