TL;DR: Palladium acetate anchored to a copolymer containing pyridyl and carboxyl groups has been employed as a catalyst for the hydrogenation of azo and nitro groups under 1 atm hydrogen pressure and 30°C.

TL;DR: In this article, a copolymer support containing pyridyl and carboxyl groups was used to anchor the palladium(II) acetate to the Copolymer Support for the hydrogenation of olefins.
Abstract: Palladium(II) acetate has been anchored onto a copolymer support containing pyridyl and carboxyl groups. XPS studies showed the Pd 3d binding energies for the recovered catalyst to be less by 1 eV after being used in hydrogenation studies. However, x-ray studies and a chemical test based on KCN treatment failed to reveal any palladium oxide or palladium metal formation in the recovered catalyst. It is presumed that an acetate ligand is lost during hydrogenation, which could be the reason for the lowering of the palladium 3d binding energies in the recovered catalyst. Results of investigations of the hydrogenation of olefins and selectivity of the catalyst toward the hydrogenation of dienes and alkynes are presented. The loss of palladium due to leaching under the reaction conditions employed was found to be very low (<1%/cycle).

TL;DR: The chiral stationary phase for high-performance liquid chromatography showed good chiral recognition ability towards various racemates, including Cu(acac)2, but not as well as in the phase for low-performance materials like Palladium.

TL;DR: It is noted that this method enables direct immobilization of metals onto polymers, and that normally unstable species such as Pd(0)(PPh3) can be kept stable by this immobilization technique, and it is expected that other metal catalysts can be immobilized using this microencapsulation technique.

TL;DR: In this article, the Suzuki cross-coupling reaction of a boronic acid and a bromoaromatic compound requires palladium catalysis, and almost identical yields were obtained in the usual conditions, with 30 mequiv.
