Hydroformylation of 1‐Octene in Supercritical Carbon Dioxide with Alkyl P‐Donor Ligands on Rhodium Using a Peracetylated β‐Cyclodextrin as a Solubiliser

Abstract

The presence of peracetylated β‐cyclodextrin in the reaction medium allowed for an increase in the solubility of rhodium species modified by alkyl P‐donor ligands in the catalytic hydroformylation of 1‐octene in supercritical carbon dioxide. These results were explained by considering an interaction between the peracetylated β‐cyclodextrin and the P‐donor ligands.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)

Tetrel, chalcogen, and CH⋅⋅O hydrogen bonds in complexes pairing carbonyl-containing molecules with 1, 2, and 3 molecules of CO2

“…4 Experimental work has been aimed toward greater understanding of the behavior of supercritical CO 2 (sc-CO 2 ) as solvent for organic compounds. [5][6][7][8][9][10] CO 2 has also been the subject of numerous computational studies. [11][12][13][14][15][16] Other efforts have added to understanding the interactions of CO 2 with various solutes, especially those containing carbonyl functional groups or aromatic systems and other heteroatoms as nitrogen, sulfur, or halogens in their compositions.…”

Cyclodextrins and their applications in aqueous-phase metal-catalyzed reactions

“…The possibility of performing substrate-selective reactions as enzymes offers a further dimension to CD-based catalysis. In the future, chemically modified CDs may also give the opportunity to promote reactions in other green solvents such as ionic liquids [26,127] or supercritical carbon dioxide [128][129][130][131].…”
