We have developed an allylic alkylation of alkanes by dual photo-HAT/nickel catalysis. In this reaction, radical-type hydrogen-atom-transfer of the alkanes is enabled by decatungstate as a photocatalyst, whereas nickel serves to cleave the C–O bond in the substrates under mild reaction conditions. This co-catalyzed reaction provides a method for direct functionalization of alkanes. Density functional theory calculations show that reductive elimination is the rate-determining step of this reaction.

镍催化实现烷烃的光化学烯丙基化

我们通过双光-HAT/镍催化开发了烷烃的烯丙基烷基化。在该反应中，烷烃的自由基型氢原子转移是通过十钨酸盐作为光催化剂实现的，而镍则用于在温和的反应条件下裂解基材中的 C-O 键。这种共催化反应提供了一种烷烃直接官能化的方法。密度泛函理论计算表明，还原消除是该反应的速率决定步骤。
