activate α-3° amines for deaminative arylation via condensation with an electron-rich aldehyde and merge this reactivity with nickel metallaphotoredox to generate benzylic quaternary centers, a common motif in pharmaceuticals and natural products. The reaction is accelerated by added ammonium salts. Evidence is provided in support of two roles for the additive: inhibition of nickel black formation and acceleration

A mild Ni-catalyzed reductive arylation of tertiaryalkylhalides with aryl bromides has been developed that delivers products bearing all-carbon quaternary centers in moderate to excellent yields with excellent functional group tolerance. Electron-deficient arenes are generally more effective in inhibiting alkyl isomerization. The reactions proceed successfully with pyridine or 4-(dimethylamino)pyridine
已经开发出一种温和的 Ni 催化的叔烷基卤化物与芳基溴化物的还原芳基化反应,以中等至优异的收率和优异的官能团耐受性提供带有全碳季铵中心的产品。缺电子芳烃通常更有效地抑制烷基异构化。该反应与吡啶或 4-(二甲氨基)吡啶一起成功进行,而咪唑鎓盐略微提高了偶联效率。
