Asymmetric Olefines Hydroformylation
CHIMIA, 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.

Exclusive Hydroformylation of Terminal Olefins: A Phosphorus-Free Ruthenium System for the Selective Functionalization of Complex Mixtures. [PDF]
Angew Chem Int Ed EnglDevelopment of a phosphorus‐free Ru/DBU catalyst enabling highly chemo‐ and regioselective hydroformylation of terminal olefins, sparing internal double bonds. Optimization of reaction parameters, ligand effects, and substrate scope including industrial feedstocks was realized.

Hydroformylation in fluorous biphasic media [PDF]
, 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.

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