摘要：
On treatment of the yttrium bis(alkyl) complex [ArNC(=CH2)C(Me)=NAr]Y(CH2SiMe3)(2)(THF) (I, Ar = C6H3-iso-Pr-2-2.6) containing an amide-imine ligand, with molecular hydrogen, hydrogenation of the C=N and C=C bonds takes place along with hydrogenolysis of Y-C bonds. The reaction is also accompanied by redistribution of nitrogen ligands and results in the formation of the yttrium complexes [ArNCH(Me)CH(Me)NAr]Y[ArN(=CH2)CH(Me)N(H)Ar](THF) (IIMeMe) and [ArNCH(Me)-C(=CH2)NAr]Y[ArN(=CH2)CH(Me)N(H)Ar](THF) containing, the monoanionic ene-amide-amine moiety [ArNC(=CH2)CH(Me)N(H)Ar](-), together with the dianionic diamide ligands [ArNCH(Me)CH(Me)NAr](2-) or [ArNCH(Me)C(=CH2)NAr](2-) (CIF file CCDC no. 1873206).
