<i>trans</i>-Chloro(1-Naphthyl)bis(triphenylphosphine)nickel(II)/PCy₃ Catalyzed Cross-Coupling of Aryl and Heteroaryl Neopentylglycolboronates with Aryl and Heteroaryl Mesylates and Sulfamates at Room Temperature

<i>trans</i>-Chloro­(1-naphthyl)­bis­(triphenylphosphine)­nickel­(II) complex/PCy₃ system has been successfully applied as catalyst for the Suzuki–Miyaura cross-coupling of aryl and heteroaryl neopentylglycolboronates with aryl and heteroaryl mesylates and sulfamates in THF at room temperature. This cross-coupling reaction tolerates various functional groups, including keto, imino, ester, ether, and cyano. Together with the nickel-catalyzed, one-pot, two-step neopentylglycolborylation, this bench stable and inexpensive Ni­(II)-based catalyst can be utilized as an alternative to Ni­(COD)₂<i>/</i>PCy₃ to provide an inexpensive, robust, and convenient synthesis of biaryl and heterobiaryl compounds
