Zirconium and titanium bis (benzamidinate) dimethyl complexes were found to be active
catalytic precursors for the oligomerization of mono-and bis-substituted silanes. The
activation of such complexes, by an excess of MAO or by an equimolar amount of B (C6F5)
3, increases the catalytic activity of the complexes and the molecular weight of the obtained
oligosilanes. The maximum polymerization index that was accomplished (n= 90) is by far the
largest obtained with other organometallic complexes. In addition, the activated …
