Two efficient protocols for the nickel-catalyzed aryl–alkyl cross-coupling reactions using esters as coupling components have been established. The methods enable the selective oxidative addition of nickel to acyl C–O and aryl C–O bonds and allow the aryl–alkyl cross-coupling via decarbonylative bond cleavage or through cleavage of a C–O bond with high efficiency and good functional group compatibility
已经建立了使用酯作为偶联组分的镍催化的芳基-烷基交叉偶联反应的两种有效方案。该方法可将镍选择性氧化添加至酰基C-O和芳基C-O键,并允许通过脱羰键裂解或通过C-O键的裂解实现芳基-烷基的交叉偶联,具有高效率和良好的官能团相容性。该协议允许在合成有机化学中简化,非常规地利用广泛的酯基及其前体,羧酸和苯酚。
