Cross-Coupling of Aryl/Alkenyl Pivalates with Organozinc Reagents through Nickel-Catalyzed C----O Bond Activation under Mild Reaction Conditions

Cross-Coupling of Aryl/Alkenyl Pivalates with Organozinc Reagents through Nickel-Catalyzed C----O Bond Activation under Mild Reaction Conditions

Finding the right partner: The catalyst system [NiCl2(PCy3)2] mediates the title transformation with high efficiency and allows aryl–aryl and vinyl–aryl coupling to proceed. The first example of catalytic cross‐coupling using the pivalates and organozinc reagents is described (see scheme; Cy=cyclohe...

Zusammenfassung:Finding the right partner: The catalyst system [NiCl2(PCy3)2] mediates the title transformation with high efficiency and allows aryl–aryl and vinyl–aryl coupling to proceed. The first example of catalytic cross‐coupling using the pivalates and organozinc reagents is described (see scheme; Cy=cyclohexyl, piv=pivalate).
