摘要：

A series of fluorocarbon-containing salicylaldimine and iminophosphine Schiff base ligands and their Rh(I) complexes were synthesized. The synthesized ligands and complexes were characterized using different analytical and spectroscopic techniques including (H-1, C-13{H-1}, P-31{H-1} and F-19{H-1} NMR spectroscopy), FT-IR spectroscopy, mass spectrometry (ESI and El), and elemental analysis. In addition, single crystal X-ray diffraction was also used for characterization for complexes 1 and 2. Consequently, the Rh(I) synthesized complexes were evaluated as catalyst precursors in the hydroformylation of 1-octene. The hydroformylation results showed that the iminophosphine and salicylaldimine-based catalyst precursors are active and selective under mild conditions, converting 1-octene to mostly aldehydes.
