6-trichlorophenoxide. The 1,3-benzdiyne equivalent also underwent the chemoselective stepwise generation of arynes and the double cycloaddition with different arynophiles. These hybrid benzdiyne equivalents provided the double cycloadducts in high yields and enabled the convenient one-pot procedure for synthesis of polycyclic aromatic compounds.
1,4-苯二炔等价物[2,5-双(三甲基甲硅烷基)-4-(三甲氧基)苯基](苯基)碘鎓三氟甲磺酸盐由2,4,5-三氯苯酚钠制备。在用氟离子处理后,观察到来自苯基碘基团一侧的芳炔的化学选择性生成。1,4-苯二炔与不同亲芳体的双环加成在一锅中进行,得到高产率的双环加合物。类似地,带有苯基碘和三氟甲磺酸酯基团的 1,3-苯二炔等效物由 2,3,6-三氯苯酚钠制备。1,3-苯二炔等价物也经历了芳炔的化学选择性逐步生成和与不同亲芳体的双环加成。
