It is shown that alkyl, alkenyl and aryl cuprates add to vinyl- triphenylphosphonium bromide to provide phosphoranes and that the Z:E ratio of their Wittig condensation products with benzaldehyde and hexanal are strongly influenced by the addition of hexamethyl- phosphoramide. This reaction is applied to the one-pot synthesis of the title compound.
结果表明,烷基,链烯基和芳基铜酸酯加到溴化乙烯基三苯基phosph上可提供膦烷,并且它们的Wittig缩合产物与苯甲醛和己醛的Z:E比例受六甲基磷酰胺的强烈影响。该反应用于标题化合物的一锅法合成。
