摘　　要：Divalent ytterbium lodide[LYb(μ-I)(THF)]2(1;L=[MeC(NDIPP)CHC(Me)NCH2CH2NMe2]^-,DIPP=2,6-(iPr)2C6H3)was synthesized and its reactivity was studied.Complex 1 was synthesized by salt metathesis of Ybl2(THF)2 with the potassium salt of ligand(KL)in high yield.In the reactions with trimethylsil azide,azobenzene,sulfur and diphenyl disufide,complex 1 acts as a 2e reductant.In the reaction with CO2,the central carbon atom ofβ-diketiminato backbone in 1 nuclephilcally attacks the CO2 molecule to give a divalent ytterbium carboxylate.
