The use of electron‐poor, fluoro‐containing arylboronic acids as general coupling partners for nickel(0)/tricyclohexylphosphine‐catalyzed cross‐coupling of aryl arenesulfonates is described. Electron‐poor fluoro‐containing arylboronic acids were found to react faster than electron‐rich/neutral arylboronic acids, with (4‐methoxyphenyl)(4‐methylbenzenesulfonato‐κO)bis(tricyclohexylphosphine)nickel. Bis(1
描述了使用贫电子的含氟芳基硼酸作为芳烃芳磺酸盐的镍(0)/三环己基膦催化的交叉偶联的一般偶联伙伴。芳基硼酸含氟缺电子被发现比富电子/中性芳基硼酸进行反应更快,(4-甲氧基苯基)(4- methylbenzenesulfonato-κ ø)双(三环己基膦)镍。双(1,5-环辛二烯)镍(0)/三环己基膦,(4-甲氧基苯基)(4- methylbenzenesulfonato-κ ø)双(三环己基膦)镍和双(三环己基膦)镍(II),溴化都发现是有效的催化剂催化剂前体。
