Asymmetric Olefines Hydroformylation
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.

Biobased Oligo- and Polyesters from Fatty Acids with Demonstrated Biodegradability or Recyclability for Industrial Applications in a Circular Economy. [PDF]
This “Perspectives”‐article describes and discusses two recent developments in the field of biobased as well as biodegradable or chemically recyclable oligomers/polymers for applications in the lubricant and plastics product segments, which are efficiently accessible and which are based on the utilization of unsaturated fatty acids as feedstocks. This “

Hydroformylation in fluorous biphasic media [PDF]
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
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
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]
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 ...
