6-Cyclopropylidene-1-hexynes like 2, e. g. prepared via palladium(0)-catalyzed substitution of 1-ethenyl cyclopropyl sulfonates 1, undergo an intramolecular Pauson-Khand reaction both efficiently and regioselectively.
诸如2的6-环丙叉基-
1-己炔,例如通过
钯(0)催化的
1-乙烯基环
丙基磺酸盐1的取代而制备的,其分子内的Pauson-Khand反应既有效地又是区域选择性的。
