A Recyclable Nanoparticle-Supported Rhodium Catalyst for Hydrogenation Reactions
Molecules, 2010 Catalytic hydrogenation under mild conditions of olefins, unsaturated aldeydes and ketones, nitriles and nitroarenes was investigated, using a supported rhodium complex obtained by copolymerization of Rh(cod)(aaema) [cod: 1,5-cyclooctadiene, aaema ...

Die Umlagerung der Addukte von Säuren an Push-Pull-Acetylene : Ihre Anwendung in der Peptid-Synthese
CHIMIA, 1979 Push-pull-acetylenes (1) react rapidly and smoothly with proton acids to yield 3-dialkylamino-3-X-acrylic derivatives, which rearrange under very mild conditions (and in the case of the adducts of carboxylic acids quantitatively) to 3-X-N,N-dialkyl ...

Cu(0)-RDRP of methacrylates in DMSO: importance of the initiator [PDF]
, 2017 The controlled radical polymerization of methacrylates via Cu(0)-mediated RDRP is challenging in comparison to acrylates with most reports illustrating higher dispersities, lower monomer conversions and poorer end group fidelity relative to the acrylic ...
