Synthetic procedures were developed for preparation of substituted alumacyclopenta-2,4-dienes and 1-ethyl-2(3)-(1-ethyl-3-alumacyclopentylmethyl)-3(2)-alkyl(phenyl)alumacyclopent-2-enes by cycloaluminizing acetylenes and 1,4-enynes using RAlCl2 (R = Et, BuO, Et2N) and Et3Al in the presence of Zr-containing catalysts (Cp2ZrCl2, ZrCl4).
在含 Zr 的催化剂(Cp2ZrCl2、ZrCl4)存在下,使用 RAlCl2(R = Et、BuO、Et2N)和 Et3Al,通过环化乙炔和 1,4-烯炔,开发了制备取代的矾杂环戊-2,4-二烯和 1-乙基-2(3)-(1-乙基-3-矾杂环戊基甲基)-3(2)-烷基(苯基)矾杂环戊-2-烯的合成程序。
