Abstract:
A new, general patterning methodology that may allow for the preparation of site-isolated organometallic catalysts on a silica surface is reported. The technique is demonstrated with Group 4 polymerization catalysts. The catalysts synthesized via the patterning method have up to a 10-fold increase in activity as compared to materials prepared by traditional techniques. In addition to supporting Group 4 polymerization catalysts, the patterned aminosilica is a possible support for other metal complexes, allowing for the synthesis of a wide array of immobilized single-site organometallic catalysts.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
