Herein, a nickel catalysis system for desulfonylative C(sp2)–C(sp2) reductive cross-coupling reactions of aryl sulfone derivatives with a range of aryl bromides has been established to form diverse biaryl compounds. The complex Ar–Ni(II)–SO2CF3 bearing a phosphine ligand through oxidative addition of aryl sulfone to Ni(0) species was isolated and confirmed by an X-ray, which provides solid evidence
在此,建立了用于芳基砜衍生物与一系列芳基溴化物的脱磺酰化 C(sp 2 )–C(sp 2 ) 还原交叉偶联反应的镍催化体系,以形成多种联芳基化合物。通过芳基砜氧化加成Ni(0)物种得到带有膦配体的Ar-Ni(II)-SO 2 CF 3络合物,分离并通过X射线证实,这为理解C( Ar)–SO 2键活化及反应机理。
