Abstract

Monovalent thulium iodide TmI as a component of a TmIx mixture at 200°С under atmospheric pressure is found to react with hydrogen with the formation of the hydrogenation product [TmIxH], 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 TmIx mixture, TmI reacts with phenol and phenylacetylene. In the first case, a poorly separable mixture of iodides–phenolates TmIx(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 TmIx with СО2.
