Alkyl(aryl)oxy derivatives of thulium(III)

The reactions of Tml2(DME)3 with phenol andtert-butyl alcohol afforded thulium(III)-alkoxyiodides ROTmI2(DME)2 (R=Ph and But, respectively). Their structures were determined by X-ray analysis. Monoiodides (RO)2 TmI(THF)2 were synthesized from TmI3 (THF)2 and ROH (taken in a ratio of 1∶2). Triphenoxides (RO)3Tm (R=Ph or 2,4,6-But3C6H2) were prepared by the reactions of the naphthalene thulium complex [C10H8Tm(DME)]2C10H8, with an excess of the corresponding phenol. The iodide catechoxide complex 3,6-But2C6H2O2TmI(DME)2 was prepared by the reaction of TmI2(DME)3 with 3,6-di-tert-butylbenzoquinone-1,2 or 3,6-di-tert-butylpyrocatechol.
