DIBAH-Mediated Amide/Hydride Transformation in ansa-Lanthanidocene(III) Complexes

Unsolvated hydride derivatives [Me2Si(2‐Me‐C9H5)2LnH] (Ln=Y, Ho) are available from ansa‐lanthanidocene complexes rac‐[{Me2Si(2‐Me‐C9H5)2}Ln{N(SiHMe2)2}] by utilizing a novel [N(SiHMe2)2]/[H] transformation inititated by diisobutylaluminumhydride (DIBAH; see scheme; R=SiHMe2). The molecular structure of the THF adduct reveals a “flyover” dimer of composition [{Y(thf)}2{μ2‐[(η5‐2‐Me‐C9H5)SiMe2(η5‐2‐Me‐C9H5)]}2(μ2‐H)2].
