摘要：

The complex activated CPh(CPh)4CPhTiBr2 has been obtained by reaction of the system C6Me6(C6H6)Ti(AlBr4)2-2Et3Al with diphenylacetylene. The titanacycloheptatriene ring is not planar, all C-C bonds are roughly equivalent and all carbon atoms are at bonding distances to titanium. The complex is a product of catalyst deactivation in which the oxidative addition of trimeric intermediate to Ti(II) results in a release of aluminium-containing ligands.
