Effector responsive hydroformylation catalysis

Distal-Selective Hydroformylation using Scaffolding Catalysis

In hydroformylation, phosphorus-based directing groups have been consistently successful at placing the aldehyde on the carbon proximal to the directing group. The design and synthesis of a novel catalytic directing group are reported that promotes aldehyde formation on the carbon distal relative to the directing functionality. This scaffolding ligand, which operates through a reversible covale...

Aqueous phase homogeneous catalysis using core–shell nanoreactors: Application to rhodium-catalyzed hydroformylation of 1-octene

High catalytic activity (turnover frequencies up to 700 h) was achieved using new triphenylphosphinefunctionalized core cross-linked micelles, TPP@CCM, as nanoreactors and [Rh(acac)(CO)2] as catalyst precursor for the aqueous biphasic hydroformylation of 1-octene. While the hydrophobic core of the polymer offers an adequate environment for the catalytic reaction, its hydrophilic shell confines ...

Diastereoisomeric bisphosphite ligands in the hydroformylation of octenes: rhodium catalysis and HP-NMR investigations.

Diastereoisomeric hydroformylation catalysts show differences for the catalyst preformation pathway and a strongly reduced n-octene hydroformylation activity for the (S,S,R)-isomer.

Solid-phase catalysis: a biomimetic approach toward ligands on dendritic arms to explore recyclable hydroformylation reactions.

The hydroformylation reaction is extensively used, on a commercial basis, to obtain linear and branched aldehydes from the reaction of alkenes with hydrogen and carbon monoxide in the presence of a catalyst (i.e., Rh, Co, etc).1 Although homogeneous catalysis has been widely practiced in the past, in most cases, the separation of the products from the reaction mixtures is a nontrivial undertaki...
