Abstract

The new divalent thulium compound [Tm(BH4)2(DME)2] could be prepared by reduction of [Tm(BH4)3(THF)3] or from TmI2 and KBH4. It was used as a precursor to the divalent [(TptBu,Me)Tm(BH4)(THF)] by reaction with potassium tris(2-tBu-4-Me)pyrazolylborate (KTptBu,Me). Both TmII compounds were found active as ε-caprolactone polymerisation catalysts.
