A Lewis base supported terminal uranium phosphinidene, [η-1,3-(MeC)CH]U(═P-2,4,6-BuCH)(OPMe) (), is isolated from the reaction of the uranium methyl chloride [η-1,3-(MeC)CH]U(Cl)Me () with 2,4,6-(MeC)CHPHK in toluene in the presence of MePO. Moreover, the reactivity of uranium phospinidene toward a series of small molecules was comprehensively explored. While no reactivity of with internal alkynes is observed attributed to steric hindrance, it readily reacts in good yields with various small molecules including isothiocyanates, aldehydes, imines, diazenes, carbodiimides, nitriles, isonitriles, and organic azides, yielding uranium sulfidos, oxidos, metallaheterocycles, and imido complexes.
一种由路易斯碱支撑的末端铀磷烯，[η-1,3-(MeC)CH]U(═P-2,4,6-BuCH)(OPMe)（），是在甲苯中，于甲基磷酸酯（MePO）存在的情况下，通过氯化铀甲基[η-1,3-(MeC)CH]U(Cl)Me（）与2,4,6-(MeC)CHPHK反应分离得到的。此外，还全面探索了铀磷烯对一系列小分子的反应活性。由于空间位阻，未观察到其与内炔烃的反应活性，但它能与包括异硫氰酸酯、醛、亚胺、重氮化合物、碳二亚胺、腈、异腈和有机叠氮化物在内的各种小分子顺利反应，产率良好，生成铀硫代物、氧化物、金属杂环和亚胺基配合物。
