When using Rh/SiO2 or Rh/NC as catalyst precursor, the conversion of benzene and propylene or toluene and 1‐pentene yields a ratio of anti‐Markovnikov to Markovnikov products that is nearly identical to the same ratios as the molecular catalyst precursor [Rh(μ‐OAc)(η2...
The best hydroformylation results were achieved at low H2:CO ratios (T = 170–240 ◦C, p = 5.0 MPa, 10% C2H4, 10% H2, 70% CO, 10% Ar, GHSV = 2773 h−1). A high CO partial pressure was necessary to suppress the olefin hydrogenation as side reaction. In the case of the ...
