Terminal arylalumylene complexes of platinum [Ar-Al-Pt(PCy3 )2 ] (Ar=2,6-[CH(SiMe3 )2 ]2 C6 H3 (Bbp) or 2,6-[CH(SiMe3 )2 ]2 -4-(tBu)C6 H2 (Tbb)) have been synthesized either by the reaction of a dialumene-benzene adduct with [Pt(PCy3 )2 ], or by the reduction of 1,2-dibromodialumanes Ar(Br)Al-Al(Br)Ar in the presence of [Pt(PCy3 )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.
铂的末端芳基烯基配合物[Ar-Al-Pt(PCy3 )2 ]（Ar=2,6-[CH(SiMe3 )2 ]2 C6 H3 (Bbp) 或 2,6-[CH(SiMe3 )2 ]2 -4-(tBu)C6 H2 (Tbb)）可通过二烯基-苯加合物与[Pt(PCy3 )2 ]的反应，或通过在[Pt(PCy3 )2 ]存在下还原 1,2-二溴二烷来合成。X 射线晶体学分析表明，这些芳基烯基配合物中的 AlPt 键长度短于先前报道的最短 AlPt 距离。DFT 计算表明，芳基烯基配合物中的 AlPt 键具有显著的高静电特性。
