磷烷 [(Me3Si)2N](Ph)PCl 与 NaCpMo(CO)3 和 NaCpW(CO)3 反应得到各自的金属磷配合物 Cp(CO)2M{P(Ph)[N(SiMe3)2]} (M = Mo (4a), W (4b))。 4a、b 与 S 和 Se 的后续反应产生了意想不到的不同产物： Cp(CO)2(S)M{P(Ph)[N(SiMe3)2]} (M = Mo (7a))； Cp(CO)2MSP(Ph)[N(SiMe3)2] (M = W (7b)); Cp(CO)2MSeP(Ph)[N(SiMe3)2]（M = Mo (8a)、W (8b)）。这些化合物已通过元素分析和光谱数据进行了充分表征，并且4a、7a、b和8a的分子结构已通过单晶X射线衍射技术确定。 7a的分子结构显示出长的末端Mo−S键，而7b和8a则含有M−E−P三元环。
The reactions of the phosphane [(Me3Si)2N](Ph)PCl with NaCpMo(CO)3 and NaCpW(CO)3 give the respective metallophosphenium complexes Cp(CO)2M{P(Ph)[N(SiMe3)2]} (M = Mo (4a), W (4b)). The subsequent reactions of 4a,b with S and Se produce unexpectedly different products: Cp(CO)2(S)M{P(Ph)[N(SiMe3)2]} (M = Mo (7a)); Cp(CO)2MSP(Ph)[N(SiMe3)2] (M = W (7b)); Cp(CO)2MSeP(Ph)[N(SiMe3)2] (M = Mo (8a), W (8b)). The compounds have been fully characterized by elemental analyses and spectroscopic data, and the molecular structures of 4a, 7a,b, and 8a have been determined by single-crystal X-ray diffraction techniques. The molecular structure of 7a displays a long, terminal Mo−S bond, while 7b and 8a contain M−E−P three-membered rings.
