Heteroleptic Tm(II) complexes: One more success for Trofimenko's scorpionates

Reaction of Tml(2)(THF)(x) with the bulky scorpionate, KTp(tBU,Me), gave (Tp(tBu,Me))Tml(THF) (1). Complex 1 proved to be a useful starting material for a select number of heteroleptic Tm(II) compounds, (Tp(tBu,Me))TmER, including the first Tm(II)-hydrocarbyl derivative, (Tp(tBu,Me))Tm(CH(SiMe3)(2)) (2).
