Reaction examples are divided by substances, and different homogeneous catalytic complexes, also different reaction mechanisms depending on used catalytic complex, are described. As a very important part, also several examples of hydroformylation reaction that uses carbon dioxide are described, together with mostly used homogeneous catalytic complexes, and reaction mechanisms. This contains reverse-water gas shift reaction, which converts carbon monoxide to carbon dioxide, and ionic liquids, which are successfully used as solvents in hydroformylation reaction. \nThe experimental part aimed to investigate the mechanism of the carbon dioxide-based hydroformylation reaction through investigating the kinetic isotope effect (KIE). Based on that, deuterated substrates were synthesized with good yields and deuteration levels, 1-deuterio-cyclohexene and 1,2,3,3-tetradeuterio-cyclohexene. Unfortunately, the deuterated substrates could not be used in the KIE-experiments, due to the lack of time for this project.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2021-03-31T06:10:06Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-03-31T06:10:06Z (GMT).
