The reaction of magnesium chloride with two equivalents of sodium phosphaethynolate, Na[OCP]·(dioxane) (1), yields a magnesium diphosphaethynolate complex, [(THF)Mg(OCP)] (3). The formation of compound 3 goes through a monosubstituted chloromagnesium phosphaethynolate Mg(OCP)Cl (2). The structure of 3 was determined via a single crystal X-ray diffraction study. For comparison, we also report the structure of a monomeric sodium phosphaethynolate complex, [Na(OCP)(dibenzo-18-crown-6)] (4).
氯化镁与两当量的膦乙炔醇钠Na[OCP]·(二氧六环) (1)反应，生成二膦乙炔醇镁配合物[(THF)Mg(OCP)] (3)。化合物3的形成经过单取代的氯代镁膦乙炔醇Mg(OCP)Cl (2)。通过单晶X射线衍射研究确定了3的结构。为作比较，我们还报道了单体膦乙炔醇钠配合物[Na(OCP)(二苯并-18-冠-6)] (4)的结构。
