Abstract
Reactions of equimolar amounts of Cp3Er or amides [(Me3Si)2N]3Ln (Ln = Y, Nd) with triethanolamine lead to the formation of insoluble products of the composition Ln(OC2H4)3N. Naphthalene complex of Eu(II), Cl10H8Eu(THF)3, reacts with triethanolamine also with the formation of insoluble compound of trivalent europium Eu(OC2H4)3N. Erbium aminoalkoxide Er(OC2H4)3N actively reacts with carbon dioxide at room temperature and atmospheric pressure in THF to form the adduct Er[OC(O)OC2H4]3N. In the reaction of triethanolamine with the excess of [(Me3Si)2N]3Ln (Ln = Y, Eu) in THF soluble binuclear complexes of the composition [(Ne3Si]2NLn(OC2H4)3NC2H4OLn[N(SiMe3)2]2(THF) are formed. The reaction of triethanolamine with [(Me3Si)2N]3Y in 3:1 ratio in THF gives the compound Y[OC2H4N(C2H4OH)2]3. The composition and structure of obtained complexes was established by elemental analysis and the IR and NMR spectroscopy.
