An efficient one-pot synthesis of bis(phospholanes) was elaborated, which included a sequential Cp2ZrCl2-catalyzed cycloalumination of α,ω-diolefins with AlEt3, giving the corresponding bis(aluminacyclopentanes), and their in situ reaction with dihalophosphines to furnish the target α,ω-bis(phospholanes). The reaction of these compounds with H2O2 or elementary sulfur gave the corresponding bis(phospholane 1-oxides) and bis(phospholane 1-sulfides).
我们详细阐述了一种高效的双(磷脂)一锅合成法,其中包括 Cp2ZrCl2 催化α,ω-二烯烃与 AlEt3 顺序环化,得到相应的双(铝环戊烷),并将其与二卤化膦原位反应,得到目标α,ω-双(磷脂)。这些化合物与 H2O2 或元素硫反应后,得到了相应的双(磷烷 1-氧化物)和双(磷烷 1-硫化物)。
