英文摘要	a series of phosphine ligands with different electron structure were directly used to modify rh/sio2 to prepare the organic-inorganic hybrid l-rh/sio2 catalysts for hydroformylation of 1-hexene. the catalytic performance of l-rh/sio2 catalysts for hydroformylation of 1-hexene was different from each other. the tof of 1 hexene to heptaldehyde over p(oph)(3)-rh/sio2 catalyst was up to 4 111 h(-1), while the selectivity for heptaldehyde over pcy3-rh/sio2 was up to 100%. the activity of l-rh/sio2 catalysts decreased in the following order: p(oph) 3-rh/sio2 > pph3-rh/sio2 > pcy3-rh/sio2, and the selectivity for heptaldehyde decreased in the reverse order. the strength of the coordination bond between l and rh decreased in the following order: pcy3rh/sio2 > pph3-rh/sio2 > p(oph)(3)-rh/sio2. these results revealed that the greater the electron donor capacity of the phosphine, the stronger is the chemical bond between l and rh, the lower is the activity of the l-rh/sio2 catalyst, and the higher is the selectivity for heptaldehyde.
