Show more >A Rh/TPPTS catalyzed aqueous biphasic hydroformylation of eugenol was performed in an aqueous medium in the presence of different modified cyclodextrins. The internal olefin such as anethole shows high selectivity towards the branched aldehydes (78%) where as terminal alkene like eugenol shows high selectivity towards the linear aldehydes (87%). The various reaction parameters such as effect of syngas pressure, time, temperature, catalyst precursor and loading have been studied. The high activity and high selectivity towards the linear aldehydes is due to the steric crowding of methyl group present in RAME-β-cyclodextrins. The effect of ratio of Rh/TPPTS/RAME-β-CD were also studied for the hydroformylation of eugenol. Moreover, this catalytic system was recycled up to four consecutive cycles without loss in its catalytic activity and selectivity.Show less >
