Asymmetric Olefines Hydroformylation

open access: yesCHIMIA, 1972
Optically active bis-(N-α-methylbenzylsalicylaldiminato)cobalt(II) and octacarbonyldicobalt in the presence of optically active N-α-methylbenzylsalicylaldimine promote asymmetric hydroformylation of styrene and α-methylstyrene.

Phosphorus coordinated Rh single-atom sites on nanodiamond as highly regioselective catalyst for hydroformylation of olefins

open access: yesNature Communications, 2021
Single-atom Rh catalysts present superior activity in olefins hydroformylation, yet with limited success in regioselectivity control. Here the authors develop a Rh1 single-atom catalyst with nanodiamond as support, with which good to excellent ...

How the coordination modes change the performance of Rh-PPh3 for complexes catalyst allyl alcohol hydroformylation: A theoretical study

open access: yesCatalysis Communications, 2023
This paper investigates the effect of coordination modes on the selectivity and activity of hydroformylation catalysts using Rhodium complexes. DFT calculations are performed on monophosphine (1P) and bisphosphine (2P) catalysts to study the impact of ...

Hydroformylation in fluorous biphasic media [PDF]

open access: yes, 2007
The hydroformylation of oct-1-ene is investigated under fluorous biphasic conditions, utilising the facile catalyst recovery that is provided by the temperature dependent miscibility of the perfluorinated solvent with normal organic solvents.

Reductive Hydroformylation of Isosorbide Diallyl Ether

open access: yesMolecules, 2021
Isosorbide and its functionalized derivatives have numerous applications as bio-sourced building blocks. In this context, the synthesis of diols from isosorbide diallyl ether by hydrohydroxymethylation reaction is of extreme interest.

Metal-organic frameworks as kinetic modulators for branched selectivity in hydroformylation

open access: yesNature Communications, 2020
The Co-catalysed hydroformylation of olefins produces selectively linear but not branched aldehydes. Here, the authors show that microporous MOFs increase the olefins density in the pores beyond neat conditions allowing high branched selectivity through ...

Kinetics of hydroformylation of 1-octene in ionic liquid-organic biphasic media using rhodium sulfoxantphos catalyst [PDF]

open access: yes, 2011
Biphasic hydroformylation of 1-octene was performed using rhodium sulfoxantphos catalyst dissolved in [BuPy][BF4] ionic liquid. Preliminary experiments proved this system to retain the catalytic complex within the ionic liquid phase and to maintain a ...
