WebTandem isomerization–hydroformylation of oleonitrile (an 18-carbon nitrile with a remote internal (9-)C=C bond) has been studied using Rh-bisphosphite catalyst systems, targeting formation of the linear aldehyde. The best compromise between regioselectivity (l/b = 58:42) and chemoselectivity (60%) was obtained at 120 °C and 10 bar CO/H2 (1:1) … WebThe precursor Rh complex exhibited Rh-CO bands at 2085 cm-1 and 2014 cm-1 and these bands disappear when BiPhePhos is introduced indicating replacement of CO by the diphosphite ligand. After H 2 is introduced, CO vibrations at 2077 and 2024 are observed consistent with the literature assignments for the Rh-hydridodicarbonyl complex.
