Abstract

Hydroformylation of 1-hexene was carried out in a high pressure reactor using water soluble [Ru(III)-EDTA] catalyst, synthesis gas (1:1) CO + H2 at 50 atm, in 80:20 ethanol-water mixture and at 130 °C. The reaction proceeds with a turnover rate of 11.83 mol product per mol catalyst per hour with the conversion of 1-hexene exclusively (100%) to linear 1-heptaldehyde.

    Using Ru3(CO)12 or Ru(methylallyl)2(COD) as precursor, combined with 1 equiv. ( vs. Ru) of a 2-phosphino-substituted imidazole ligand, at a [olefin]/[Ru] ratio of 167, 130 °C and 60 bar CO/H2 (1:5), they achieved full conversion of 1-octene (overall TOF = 0.13 min−1) to provide 87% of alcohol (l/b = 10), along with 9% of octane and less than 1% of the intermediate aldehyde [13,14]. In previous studies, we reported the use of Rh-Biphephos [15] and Ir-Biphephos [5][5c] catalyst systems for the tandem isomerization-hydroformylation [16,17] of the unsaturated fatty nitrile 10-undecenitrile (1) (Scheme 1), as a route toward biosourced polyamide-12.
