摘要：

Three Ti-M-2 (M-2=Ni, Pd, Pt) heterobimetallic complexes, [(eta(3-)methallyl) M-2((Ph2PNBu)-Bu-t)(2)TiCl2](OTF), were synthesized in which a Ti-IV <- M-2 interaction was suggested by crystallography and DFT calculations. The Ti-IV <- M-2 interaction enhanced electrophilicity of the eta(3)-methallyl ligand of M-2, leading to high reactivity of the eta(3)-methallyl moiety with Et2NH compared with that of the dppp analogue.
