Reactivity of monovalent thulium

It was found that monovalent thulium iodide TmI in the TmIx mixture reacts with hydrogen at 200°C and atmospheric pressure, forming a hydrogenation product [TmIxH], which is confirmed by the reaction with (C6F5)3GeBr, leading to the formation of (C6F5)3GeН. In the reaction with nitrogen at 450°C, a mixture is formed containing diiodide TmI2 and a product of the composition [Tm4IN], containing a Tm–N valence bond. TmI in the TmIx mixture also reacts with phenol and phenylacetylene. In the first case, a difficult-to-separate mixture of iodide phenolates TmIx(OPh)y is formed. The reaction with PhC≡CH leads to the formation of styrene, diphenylbenzene and a mixture of triphenylbenzenes. In the reaction of TmIx with СО2, trivalent thulium iodioxalate (C2O4)TmI(DМЕ).was isolated with a high yield.
