The cyclic alkyl(amino) carbene-anchored silylene-phosphinidene was isolated as L-Si-P(:cAAC-Me) (L=benzamidinate) at room temperature, synthesized from the reduction of L-Si(Cl )-P(:cAAC-Me) (1) using two equivalents of KC . Compound 1 was prepared by the oxidative addition of a chlorophosphinidene to the benzamidinate substituted silylene center. This is the first molecular example of a silylene-phosphinidene characterized by single-crystal X-ray structural analysis. Moreover, H, P, and also Si NMR spectroscopic data supported the formulation of the products. The theoretical calculations of compound 2 are in good agreement with the experimental results.
环状烷基(氨基)碳烯锚定的硅亚膦烯被分离为 L-Si-P(:cAAC-Me)（L=苯甲脒），在室温下，通过使用两当量的 KC 还原 L-Si(Cl )-P(:cAAC-Me)（1）合成。化合物 1 是通过氯膦亚膦烯对苯甲脒取代的硅亚膦烯中心的氧化加成反应制备的。这是首例通过单晶 X 射线结构分析表征的硅亚膦烯分子实例。此外，氢、磷和硅 NMR 光谱数据也支持产物的结构。化合物 2 的理论计算与实验结果吻合良好。
