A novel germinal germanium/phosphorus frustrated Lewis pair, Cl₃GeCH₂P^tBu₂ 1, was prepared through the metathesis reaction of ^tBu₂PCH₂Li with tetrachlorogermanium. This neutral germanium-based frustrated Lewis pair 1 exhibits higher reactivity toward a series of small molecules. When 1 was treated with an excess amount of tetrachloromethane (2.3equiv) yielding a zwitterionic adduct 2, Cl₄GeCH₂P(Cl)^tBu₂. The cycloaddition of dimethyl but-2-ynedioate with 1 was took place smoothly at room temperature, and afforded a zwitterionic cyclic vinyl 3 in good yields. The reaction of 1 with furan-2,5-dione has also been performed giving the corresponding cycloaddition 4 in high yields. The additions of C=Ch (Ch = O, and S) units involving 1-isocyanato-4-methylbenzene and isothiocyanatobenzene with 1 have been also carried out at ambient temperature in which the five-membered GeCPCO(S)-ring products 5a and 5b were furnished, respectively. All these above-mentioned compounds 1-5 were fully characterized by multinuclear NMR spectroscopy, high-resolution mass spectrometry (HRMS), and the structures of 1 and 3 were also determined by single-crystal X-ray diffraction.

通过^t Bu ₂ PCH ₂ Li与四氯锗的复分解反应制备了一种新型的锗/磷受挫Lewis对Cl ₃ GeCH ₂ P ^t Bu ₂ 1。这种基于中性锗的受挫路易斯对1对一系列小分子表现出更高的反应性。当1用过量的四氯甲烷（2.3当量）处理时产生两性离子加合物2，Cl ₄ GeCH ₂ P(Cl) ^t Bu ₂。丁-2-炔二酸二甲酯与1在室温下顺利进行，并以良好的产率得到两性离子环状乙烯基3。1与呋喃-2,5-二酮的反应也已进行，以高产率得到相应的环加成4。涉及 1-异氰酸根合-4-甲基苯和异硫氰酸根合苯与1的 C=Ch（Ch=O，和 S）单元的加成也在室温下进行，其中五元 GeCPCO(S)-环产物5a和分别配备了5b。所有上述化合物1-5均通过多核 NMR 光谱、高分辨率质谱 (HRMS) 和结构图 1和图3也通过单晶 X 射线衍射测定。
