Notes:
The methylhafnocene cation 2a reacts with bispropynylzirco-nocene to give a single regioisomeric planar-tetracoordinate carbon compound (4a) that contains the hafnium atom singly-bonded and the zirconium center η2-coordinated to the bridging μ-(η1-C:η2-C,C-2-butyne) ligand. However, the reaction between the methylzirconocene cation 2b with bis(phenylacetylide)hafnocene (3b) gives the pure regioiso-mer 4b with an opposite relative arrangement of the two group 4 transition metals (the methyl is at the planar-tetra-coordinate carbon atom C2). Complex 4a was characterized by an X-ray crystal structure analysis.
