We herein demonstrate that the amide base generated in situ from CsF and N(TMS)3 catalyzes the deprotonative coupling reactions of terminal alkynes with polyfluoroarenes, wherein mono‐ and dialkynylations occur efficiently for penta‐ and hexafluorobenzenes, respectively. Tetraalkynylated products could also be synthesized from dialkynylated compounds.
我们在本文中证明了从CsF和N(TMS)3原位生成的酰胺基催化末端炔烃与多氟芳烃的去质子偶联反应,其中五氟苯和六氟苯分别发生单和二炔基化反应。四烷基化产物也可以由二烷基化化合物合成。
