Study on catalysts and reaction process for highly selective hydroformylation of 1-octene

上海师范大学学报. 自然科学版
Using rhodium dicarbonylacetylacetonate as the rhodium(Rh) catalyst precursor, the catalytic performances of different monodentate and bidentate phosphine ligands, bisphosphite ligands, and the self-synthesized ligand system Rh-L9 were investigated in ...

Synthesis of (–)-Indolizidine 167B based on domino hydroformylation/cyclization reactions

Beilstein Journal of Organic Chemistry, 2008
The synthesis of (–)-Indolizidine 167B has been achieved from optically active (R)-3-(pyrrol-1-yl)hex-1-ene. The key step is a highly regioselective hydroformylation reaction and a one-pot intramolecular cyclization providing a general approach to the ...

Hydroformylation of Limonene

Journal of Japan Oil Chemists' Society, 1973
Hydroformylation of limonene has been studied using cobalt carbonyl and rhodium carbonyl catalysts under “oxo reaction” conditions. The aimed β- (4-methyl-Δ3-cyclohexenyl) -butylaldehyde was obtained with theoretical yields of 42 and 52% based on limonene by using bis- (cobalt tricarbonyl tributylphosphine) complex and rhodium carbonyl catalysts ...

Organophotoredox/Cobalt‐Catalyzed Retro‐Hydroformylation of Aldehydes

ChemistryEurope
A new cobalt/organophotoredox dual catalytic system is reported for the efficient retro‐hydroformylation of aldehydes. Under the optimized conditions, a wide range of α‐monosubstituted aldehydes are readily transformed into the desired alkenes in a one ...
