Hydrosilylation of secondary and tertiary amides to amines is described using catalytic amounts of B(C6F5)3. The organic catalyst enables the reduction of amides with cost-efficient, non-toxic and air stable PMHS and TMDS hydrosilanes. The methodology was successfully extended to the more challenging reduction of primary amides.
While the iron is hot: The first general and efficient iron‐catalyzed reduction of secondary and tertiary amides into amines using polymethylhydrosiloxane (PMHS) has been developed (see scheme).

establishing C(sp3)–N bonds from alkyl substrates in cross-couplingchemistry using palladium and nickel catalysts. Therefore, the methods of constructing C(sp3)–N bonds remain rare from alkyl electrophiles. The existing routes are limited to copper catalysis and photoredox catalysis. Here, we demonstrate an alternative amination strategy for rapid construction of C(sp3)–N bonds from accessible alkyl electrophiles
双分子亲核取代S N 2 是烷基亲电试剂胺化最早也是最重要的手段;其实际应用很大程度上限于初级或活化基质。此外,持续的挑战在于使用钯和镍催化剂在交叉偶联化学中从烷基底物建立C(sp 3 )–N键。因此,从烷基亲电子试剂构建C(sp 3 )–N键的方法仍然很少。现有的路线仅限于铜催化和光氧化还原催化。在这里,我们展示了一种替代的胺化策略,用于从可接近的烷基亲电子试剂中快速构建 C(sp 3 )–N 键,该策略在镍催化下通过 Ni (III) 物种高效还原消除用作自由基前体。
