posted on 1997-09-30, 00:00 authored by Stefan Fokken, Thomas P. Spaniol, Jun Okuda, Fritz G. Sernetz, Rolf MülhauptTetravalent titanium complexes containing
the ethylene-linked bis(phenolato) ligand ebmp
exhibit
a C2-symmetric conformation according to
single-crystal
X-ray structural analyses. In solution, a fluxional
process equivalent to an enantiomerization is detected.
Upon activation with methylaluminoxane, these complexes copolymerize ethylene and styrene with remarkably high incorporation of styrene.
