Abstract

Monovalent thulium iodide TmI as a component of a TmI_x mixture at 200°С under atmospheric pressure is found to react with hydrogen with the formation of the hydrogenation product [TmI_xH], which is confirmed by the reaction with (C₆F₅)₃GeBr affording (C₆F₅)₃GeН. The reaction with nitrogen at 450°С affords a mixture containing diiodide TmI₂ and the product [Tm₄IN] bearing the Tm^–N valence bond. Being a component of the TmI_x mixture, TmI reacts with phenol and phenylacetylene. In the first case, a poorly separable mixture of iodides–phenolates TmI_x(OPh)_y is formed. The reaction with PhC≡CH affords styrene, diphenylbenzene, and a mixture of triphenylbenzenes. Trivalent thulium iodide–oxalate (C₂O₄)TmI(DМЕ) is isolated in a high yield from the reaction of TmI_x with СО₂.

单价铥的反应性

一价碘化铥TmI作为TmIx混合物的组成部分，在200°С大气压下与氢反应生成加氢产物[TmIxH]，与（C6F5）3GeBr反应生成（C6F5）3GeН证实了这一点。与氮气在450°С下反应，得到含有二碘化物TmI2和带有Tm-N价键的产物[Tm4IN]的混合物。作为TmIx混合物的组成部分，TmI与苯酚和苯乙炔反应。在第一种情况下，形成一种难以分离的碘-苯酚混合物TmIx(OPh)y。与PhC≡CH反应生成苯乙烯、二苯苯和三苯苯的混合物。通过TmIx与СО2反应，以高收率分离出三价草酸碘化铥（C2O4）TmI（DМЕ）。
