Rh-catalyzed linear hydroformylation of styrene.
Usually the Rh-catalyzed hydroformylation of styrene predominantly yields the branched, chiral aldehyde. An inversion of regioselectivity can be achieved using strong π-acceptor ligands. Binaphthol-based diphosphite and bis(dipyrrolyl-phosphorodiamidite) ligands were applied in the Rh-catalyzed hydroformylation of styrene. High selectivities up to 83% of 3-phenylpropanal were obtained with 1,1-...
متن کاملCHEMOSELECTIVITY AND REGIOSELECTIVITY IN HYDROFORMYLATION The control of chemoselectivity is a fundamental concern in Rh-catalyzed hydroformylation
1 RHODIUM-CATALYZED STEREOSELECTIVE HYDROFORMYLATION Reported by Daniel Robbins October 16, 2008 INTRODUCTION Hydroformylation, the conversion of olefins into aldehydes through the addition of CO and H2, is an important industrial reaction that employs homogeneous catalysis by transition metals (Figure 1). Hydroformylation is a valuable reaction in organic chemistry because it produces aldehyde...
متن کاملBiphasic hydrogenation over PVP stabilized Rh nanoparticles in hydroxyl functionalized ionic liquids.
Polyvinyl pyrrolidone stabilized rhodium nanoparticles are highly soluble in hydroxyl-functionalized ionic liquids, providing an effective and highly stable catalytic system. In hydrogenation reactions, excellent results were obtained, and transmission electron microscopy, solubility determinations, and leaching experiments were employed to quantify the advantages of this catalytic system.
متن کاملKinetics of hydroformylation of 1-octene in ionic liquid-organic biphasic media using rhodium sulfoxantphos catalyst
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 high selectivity towards the linear aldehyde (n:iso ratio of 30) over several cycles. Process parameter investigation showed a first order depende...
متن کاملBiphasic hydroformylation in ionic liquids: interaction between phosphane ligands and imidazolium triflate, toward an asymmetric process.
Biphasic hydroformylation of dec-1-ene and styrene, at commercially competitive rates, can be successfully performed in imidazolium triflate ionic liquids; the ionic liquid network forms 'inclusion complexes' with the phosphane ligands used to modify the rhodium catalyst.
