Notes:
A Simple Synthesis of Dimetallic Zirconium/Aluminium Compounds Containing Planar-Tetracoordinate Carbon(η2-Alkyne)(trimethylphosphane)zirconium complexes [alkyne = cyclohexyne (3a) or diphenylacetylene (3b)] react with diisobutylaluminium hydride at room temperature by PMe3 cleavage and addition of H—Al(isobutyl)2 to the in situ-generated (η2-alkyne)ZrCp2 intermediate to give the dimetallic Zr,Al compounds 4. These thermodynamically stable complexes contain a planar-tetracoordinate carbon center whose uncommon coordination geometry is stabilized by a combination of the s̰-donor interaction with both electropositive metals and the π-conjugation of the Zr—C = C moiety.
