Alkyl(aryl)oxy derivatives of thulium(III)

The reactions of Tml(2)(DME)(3) with phenol and tert-butyl alcohol afforded thulium(ln) alkoxyiodides ROTml(2)(DME)(2) (R = Ph and Bu-t, respectively) . Their structures were determined by X-ray analysis. Monoiodides (RO)(2)Tm l(THF)(2) were synthesized from Tml(3)(THF)(2) and ROH (taken in a ratio of I : 2). Triphenoxides (RO)(3)Tm (R = Ph or 2,4,6-(Bu3C6H2)-C-t) were prepa red by the reactions of the naphthalene thulium complex [C10H8Tm(DME)](2)C1 0H8 with an excess of the corresponding phenol. The iodide catechoxide comp lex 3,6-Bu(2)(t)C(6)H(2)O(2)Tml(DME)(2) was prepared by the reaction of Tml (2)(DME)(3) with 3,6-di-tert-butylbenzoquinone-1,2 or 3,6-di-tert-butylpyro catechol.
