Kinetische Untersuchungen zur Hydrierung von Kohlendioxid zu Ameisensäure mit einem Rhodiumkomplex als Katalysator

Kinetic Studies on the Hydrogenation of Carbon Dioxide to Formic Acid using a Rhodium Complex as Catalyst A detailed kinetic analysis has been performed on the hydrogenation of carbon dioxide with the complex [(dppp)2RhH] (dppp = 1,3-bis(diphenyl-phosphino)propane in DMSO using stopped-flow techniques. Activation parameters including the activation volume for this reaction as well as for the related reaction of the formation of the dihydrogen complex [(dppp)2RhH2]HCO2 were obtained and thus allowed the formulation of a mechanism for this reaction cycle.
