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
反式-氯(1-萘基)双(三苯基膦)镍(II)配合物/ PCy 3体系已成功用作Suzuki-Miyaura的芳烃和杂芳基新戊二醇硼酸酯与芳基和杂芳基甲磺酸酯和氨基磺酸酯的Suzuki-Miyaura交叉偶联室内温度。这种交叉偶联反应可耐受各种官能团,包括酮基,亚氨基,酯基,醚基和氰基。与镍催化的一锅两步新戊基糖基化反应一起使用,这种台式稳定且廉价的Ni(II)基催化剂可以用作Ni(COD)2 / PCy 3的替代品,从而提供廉价,坚固,方便地合成联芳基和杂联芳基化合物。
