摘要：
Activity of pyrazole ligands in hydroformylation of a number of unsaturated terminal substrates in supercritical carbon dioxide (scCO2) in the presence of Rh-catalyst was studied. The ligands without free NH group at position 1 of the pyrazole ring were found to be active. The use of scCO2 as the reaction medium served to reach a higher conversion and regioselectivity of hydroformylation as compared to those in toluene.
