Novel ‘one-pot’ catalytic methods for the synthesis of cyclopentanols, tetrahydrothiophenes, silacyclopentanes and phospholanes are based on successive transformations of olefins and organoaluminium compounds (R2AlR′) in the presence of Cp2ZrCl2 catalyst. In situ generated aluminacyclopentanes serve as common intermediates in these processes.
用于合成环戊醇,四氢噻吩,硅环戊烷和膦酸酯的新型“一锅法”催化方法是基于在Cp 2 ZrCl 2催化剂存在下烯烃和有机铝化合物(R 2 AlR')的连续转化。原位生成的氧化铝环戊烷在这些过程中用作常见的中间体。
