Selbstimmobilisierende Metallocenkatalysatoren
Peifer, Bernd,Milius, Wolfgang,Alt, Helmut G.
, p. 205 - 220 (1998)
A novel method for the preparation of heterogeneous metallocene catalysts is described that can be applied for the polymerization of olefins starting with homogeneous metallocene complexes. For this purpose zirconocene dichloride complexes have been prepared containing alkenyl or alkynyl substituents. These complexes can be activated with methyl alumoxane (MAO) and then are incorporated as comonomers into the formed polyolefin chain. The homogeneous metallocene catalysts become self-immobilizing under the reaction conditions and the further formation of the polyolefin is then catalyzed heterogeneously.
Effect of ether on regioselectivity in hydrosilylation of 1,5-hexadiene with chlorohydrosilanes catalyzed by homogeneous platinum catalysts

experimental part, p. 1556 - 1563 (2009/10/14)
Hydrosilylation of 1,5-hexadiene with chlorohydrosilanes catalyzed by homogeneous platinum catalyst to produce 5-hexenylchlorosilanes was studied. The presence of ether additives was highly effective in improving the regioselectivity and the yield. The formation of a double-bond rearrangement isomer, cis-, or trans-4-hexenylchlorosilanes, during the hydrosilylation was reduced drastically, as well. Copyright Taylor & Francis Group, LLC.
