The novel synthetic method is described for preparation of not only 1-bromo- but 1,3-dibromo-1-trifluoromethylated allenes from the corresponding propargylic alcohols with a combination of CBr4 and Ph3P. Selection of the organic solvent employed enabled us to access to these two different allenes quite readily.
本文介绍了一种新的合成方法,它不仅可以用 CBr4 和 Ph3P 从相应的丙炔醇中制备 1-溴和 1,3-二溴-1-三氟甲基烯。有机溶剂的选择使我们能够很容易地获得这两种不同的烯。
