Terminal arylalumylene complexes of platinum [Ar‐Al‐Pt(PCy 3 ) 2 ] (Ar=2,6‐[CH(SiMe 3 ) 2 ] 2 C 6 H 3 (Bbp) or 2,6‐[CH(SiMe 3 ) 2 ] 2 ‐4‐( t Bu)C 6 H 2 (Tbb)) have been synthesized either by the reaction of a dialumene–benzene adduct with [Pt(PCy 3 ) 2 ], or by the reduction of 1,2‐dibromodialumanes Ar(Br)Al‐Al(Br)Ar in the presence of [Pt(PCy 3 ) 2 ]. X‐Ray crystallographic analysis reveals that the AlPt bond lengths of these arylalumylene complexes are shorter than the previously reported shortest AlPt distance. DFT calculations suggest that the AlPt bonds in the arylalumylene complexes have a significantly high electrostatic character.
