摘要：Rh nanoparticles used as catalysts for hydroaminomethylation reaction is reported for the first time. An efficient and recyclable Rh nanoparticle catalyst stabilized by thermoregulated ligand Ph2P(CH2CH2O)(n)CH3 (n = 16) was studied for the hydroaminomethylation of olefins in the aqueous/1-butanol biphasic system through thermoregulated phase-transfer catalysis, which allows not only for a homogeneous catalytic reaction, but also for an easy biphasic separation. Under the optimized conditions, the conversion of 1-octene and the product amine selectivity were as high as 99% and 97%, respectively. After reaction, the Rh nanoparticle catalyst can be separated from products by simple phase separation and recycled directly for the next run. (C) 2013 Elsevier B.V. All rights reserved.
