A new biogenerated Rh-based catalyst for aqueous biphasic hydroformylation

A new bio-generated rhodium based system embedded in a peculiar polysaccharide matrix (Rh-EPS), was obtained and purified from cultures of bacterial cells of Klebsiella oxytoca DSM 29614. The product was analyzed with different techniques to obtain information on its structure-property correlation. In order to determine its catalytic activity and selectivity in the aqueous biphasic hydroformylation some olefins were chosen as model substrates, obtaining fine-good results.

Rh-catalyzed highly regioselective hydroformylation to linear aldehydes by employing porous organic polymer as a ligand

In this work, we developed a new structural porous organic polymer containing biphosphoramidite unit, which can be used as a solid bidentate phosphorous ligand for rhodium-catalyzed solvent-free higher olefins hydroformylation. The resultant catalyst demonstrated unprecedently high regioselectivity to linear aldehydes and could be readily recovered for successive reuses with good stability in both catalytic activity and regioselectivity.

Method for high-selectivity preparation of normal aldehyde through olefin two-phase hydroformylation on basis of phosphine-functionalized polyether imidazolium salt ionic liquid

The invention relates to a method for high-selectivity preparation of normal aldehyde through olefin two-phase hydroformylation on the basis of a phosphine-functionalized polyether imidazolium salt ionic liquid. According to the method, a two-phase catalytic system is adopted, the catalytic system comprises a phosphine-functionalized polyether imidazolium salt ionic liquid, a polyether imidazolium salt ionic liquid, a rhodium catalyst, a reaction substrate olefin and a reaction product aldehyde, a liquid/liquid two-phase hydroformylation reaction is performed at certain reaction temperature and under certain synthesis gas pressure, the rhodium catalyst is separated and cycled through simple two-phase separation after the reaction ends, the rhodium catalyst can be recycled multiple times, and the catalytic activity and the selectivity are not remarkably reduced. The TOF value of the system reaches 400-3,300 h and the catalytic cycle accumulated TON value reaches 33,975.
