Abstract

The use of the bulky cyclopentadienyl ligand Cp′ (Cp′ = C₅Me₄SiMe₃) to stabilize cerium hydrides has resulted in the preparation of two novel tuck-in complexes with C–H activated SiMe₃groups. Subsequent reaction of these with H₂in thf gives a lanthanide terminal hydride species Ce(Cp′)₂(H)(thf) which reversibly regenerates the tuck-in complex under sustained vacuum. This compound is only the second structurally characterized terminal cerium hydride. This new hydride is a catalyst in H/D exchange reactions between with both sp³-CH and sp²-CH bonds, and for the hydrogenation of unsaturated alkene bonds.
