A soluble polymer-supported ruthenium nanoparticle catalyst (NCPS-Ru 1 ) was prepared from [RuCl 2 (PhCO 2 Et)] 2 (0.1 g) and non-cross-linked polystyrene (NCPS) (0.5 g). The catalyst was used in the intramolecular carbenoid C-H insertion reaction of α-diazoacetamides. Thus, the C...
Supported olefin, e.g., alpha-olefin, polymerization catalyst compositions, such as Ziegler-Natta catalysts, are modified by using porous, polymer particles having an average pore diameter of at least about 10 Å as the catalyst support. The resulting catalyst composition is more active than...
