摘要：

The ionic Rh(III) -complexes la and 2a exhibited poor catalytic performance for hydroformylation of 1-octene without the presence of any auxiliary additive. The involvement of cheap and low-toxic tertiary amines such as Et3N or N-methylpiperidine could dramatically boost the catalytic performance of compounds la and 2a up to turnover frequency(TOF) of 800 h(-1). When piperidinyl-functionalized ionic liquid of [PEmim] BF4 was dually used as the additive and the solvent, not only the positive roles of N-methylpiperidine in spurring up the activity of compounds la and 2a were embodied, but also the easy recovery and recycling of compounds la(or 2a) in [PEmim] BF4 were fulfilled in biphasic hydroformylation. The TOFs of compounds la and 2a in [PEmin] BF4 were gradually decreased in the course of the recycling uses due to the leaching and deactivation of the catalysts.
