用甲基氯钍化合物[η - 5-1,3-(Me3C)2C5H3]2Th(p -2,4,6- ipr3c6h2phk]2Th(Cl)Me(1)与2,4,6- ipr3c6h2phk在甲苯中进行盐复分解反应，得到了kcl桥接的磷酸二代茂金属钍{[η - 5-1,3-(Me3C)2C5H3]2Th(Cl)Me(1)}2(2)。并对其分子结构进行了全面表征。研究了2对各种有机小分子的反应性，如与炔烃、腈、CS2、喹啉、硅烷、吡啶和咪唑衍生物反应，生成金属环、咪唑、碳二硫酸酯和磷酸化合物。通过密度泛函理论（DFT）计算来补充实验研究。
The KCl-bridged phosphinidiide thorium metallocene, {[η5-1,3-(Me3C)2C5H3]2Th(P-2,4,6-iPr3C6H2)(ClK)}2 (2), was isolated in good yield by a salt metathesis reaction of the thorium methyl chloride compound [η5-1,3-(Me3C)2C5H3]2Th(Cl)Me (1) with 2,4,6-iPr3C6H2PHK in toluene. Furthermore, it was fully characterized including its molecular structure. The reactivity of 2 towards various small organic molecules was also explored, e.g., it reacts with alkynes, nitriles, CS2, quinolines, silanes, pyridine and imidazole derivatives, resulting in metallacycles, imidos, carbodithiolates, and phosphido compounds. Density functional theory (DFT) computations were conducted to supplement the experimental investigations.
