Abstract

Three Ti-M₂ (M₂ = Ni, Pd, Pt) heterobimetallic complexes, [η³-methallyl)M₂(Ph₂PN ^tBu)₂TiCl₂](OTf), were synthesized in which a Ti^IV←M₂ interaction was suggested by crystallography and DFT calculations. The Ti^IV←M₂ interaction enhanced electrophilicity of the η³-methallyl ligand of M ₂, leading to high reactivity of the η³-methallyl moiety with Et₂NH compared with that of the dppp analogue.
