Summary:On treatment of the yttrium bis(alkyl) complex [ArNC(=CH 2 )C(Me)=NAr]Y(CH 2 SiMe 3 ) 2 (THF) ( I , Ar = C 6 H 3 - 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(=CH 2 )CH(Me)N(H)Ar](THF) ( II MeMe ) and [ArNCH(Me)-C(=CH 2 )NAr]Y[ArN(=CH 2 )CH(Me)N(H)Ar](THF) containing, the monoanionic ene-amide-amine moiety [ArNC(=CH 2 )CH(Me)N(H)Ar] − , together with the dianionic diamide ligands [ArNCH(Me)CH(Me)NAr] 2− or [ArNCH(Me)C(=CH 2 )NAr] 2− (CIF file CCDC no. 1873206).
