a Data showing the performances of various catalysts in the hydroformylation of styrene. b, c Data showing the performances of Rh/S1-OH and Rh/S-1 catalysts in the hydroformylation of hexene and ethylene. Reaction conditions: syngas with a molar ratio of CO to H2 at 1 (molar ratio of CO/H2/Ar at 45/45/10), 30 mg of catalyst, 2.5 mmol of styrene and 1-hexene, 5 mL of toluene as solvent, butanol as internal standard, 110 °C, 4 h. For ethylene hydroformylation, 0.5 MPa of ethylene and 2.4 MPa of syngas were employed. 0.1 MPa of methane was used as an internal standard. The carbon balances were over 99.5% for all the tests. d TOF comparison between Rh/S1-OH and different Rh catalysts tested previously in the hydroformylation of styrene. These tests were performed under comparable reaction temperatures of 100–110 °C. The details for the catalysts tested previously are summarized in Supplementary Table 2. e TOF comparison between Rh/S1-OH and Rh catalysts tested previously in the hydroformylation of LAOs. The details for the catalysts tested previously are summarized in Supplementary Table 2.
