- Enantioselective Conjugate Addition of Stabilized Arylzinc Iodide to Enones: an Improved Protocol of the Hayashi Reaction
-
Stabilised arylzinc iodide, prepared by direct insertion of zinc into aryl iodides, were used as nucleophiles in the Hayashi Rh-catalysed enantioselective conjugate addition to enones. The reaction conditions were optimized in the addition of phenylzinc i

- Ni-Catalyzed Regioselective Dicarbofunctionalization of Unactivated Olefins by Tandem Cyclization/Cross-Coupling and Application to the Concise Synthesis of Lignan Natural Products
-
We disclose a (terpy)NiBr2-catalyzed reaction protocol that regioselectively difunctionalizes unactivated olefins with tethered alkyl halides and arylzinc reagents. The reaction shows an excellent functional group tolerance (such as ketones, es

- Ultrasound-Promoted Synthesis of Arylzinc Compounds Using Zinc Powder and Their Application to Palladium(0)-Catalyzed Synthesis of Multifunctional Biaryls
-
Arylzinc compounds containing electron-withdrawing groups such as CO2CH3, CON(CH3)2, CN, Br, Cl, or CF3 at ortho position were prepared readily by the ultrasound-promoted reaction of aryl iodides with zinc powder, which were applied to palladium(0)-catalyzed cross-coupling with aryl halides to afford unsymmetrical and multifunctional biaryls in good yields.
