Ligand-induced suppression of undesirable pathways in cobalt-catalyzed hydroformylation

Hydroformylation, an industrial process yielding over 10 million tons of oxo-alcohols annually, faces increasing economic pressures linked to rhodium-based catalysts, particularly in propene hydroformylation.

Rhodium-catalyzed hydroformylation using hindered phosphine ligands: an in situ study

, 2010
Ligands behaving badly: A series of hindered biaryl phosphine compounds are used as ligands in rhodium-catalyzed hydroformylation. In situ analysis of the resultant catalysts under operating conditions shows that the ligands are dissociated under high ...

Application of a Chiral Scaffolding Ligand in Catalytic Enantioselective Hydroformylation

, 2016
The synthesis of β-amino-aldehydes has been achieved through enantioselective hydroformylation of PMP-protected allylic amines. The reaction is accomplished by using a scalemic scaffolding ligand that covalently and reversibly binds to the substrate ...
