In the February issue of Cell Reports Physical Science, Melen and co-workers report the reactivity of diaryl-substituted esters with R₃P/B(C₆F₅)₃ frustrated Lewis pairs (FLPs). Although ester C–O activation occurs for all FLP systems, the use of Mes₃P induces single-electron transfer to generate a [Mes₃P]^⋅+/[C(H)Ar₂]^⋅ radical ion pair. In the presence of olefins, this reactivity is harnessed in an sp²-sp³ C–C heterocoupling reaction to generate α,β-substituted olefins.

自由基FLP方法进行CC耦合

在《Cell Reports Physical Science》的2月号中，Melen和同事报告了二芳基取代的酯与R ₃ P / B（C ₆ F ₅）₃沮丧的Lewis对（FLP）的反应性。尽管所有FLP系统都发生酯C–O活化，但Mes ₃ P的使用会诱导单电子转移，从而生成[Mes ₃ P] ^⋅+ / [C（H）Ar ₂ ] ^⋅自由基离子对。在烯烃的存在下，这种反应性在sp ² - sp ³ C–C杂耦合反应中得到利用，生成α，β-取代的烯烃。
