efficient reductive dicarbofunctionalization of unactivated alkenes with alkyl halides and malononitriles. The combination of Ni electron-shuttle catalysis with Eu(OTf)3, a non-redox-type Lewis acid, effectively activates the iminyl radicals, enabling the direct formation of the C(sp3)–C(sp3) bond and β-ketonitrile functionality across a variety of C═C double bonds. This reaction allows for the expedient
开发了一种二元 Ni/Eu 催化系统,该系统能够利用烷基卤和丙二腈对未活化的烯烃进行有效的还原双碳官能化。 Ni电子穿梭催化与非氧化还原型路易斯酸Eu(OTf) 3的结合,有效激活亚胺基自由基,从而能够直接形成C(sp 3 )–C(sp 3 )键和β -酮腈官能团跨越各种C=C双键。该反应可以方便地合成带有全碳四元中心的密集官能化环状β-酮腈。
