The first synthesis of hexa(furan-2-yl)benzene derivatives is described. The RhCl3/i-Pr2NEt-catalyzed cyclotrimerization of di(furan-2-yl)acetylenes was an effective method for constructing hexa(furan-2-yl)benzene derivatives in good yields. Their π-extended derivatives were also synthesized by Suzuki–Miyaura coupling between hexakis(5-Bpinfuran-2-yl)benzene (Bpin = (pinacolato)boryl) and several aryl
描述了六(呋喃-2-基)苯衍生物的第一次合成。RhCl 3 / i -Pr 2 NEt催化的二(呋喃-2-基)乙炔环三聚反应是一种高效制备六(呋喃-2-基)苯衍生物的有效方法。它们的π延伸衍生物也通过Suzuki-Miyaura在六(5-Bfurfuran-2-yl)苯(Bpin =(频哪醇)硼烷基)和几种芳基碘化物之间的偶联而合成。
