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)nCH3 (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
首次报道了用作氢氨甲基化反应催化剂的Rh纳米粒子。通过温度调节配体Ph 2 P(CH 2 CH 2 O)n CH 3稳定的高效可循环利用的Rh纳米颗粒催化剂(n = 16)研究了通过温度调节相转移催化在水/ 1-丁醇双相体系中烯烃的氢氨甲基化,该方法不仅可以进行均相催化反应,而且还易于进行双相分离。在优化的条件下,1-辛烯的转化率和产物胺的选择性分别高达99%和97%。反应后,可以通过简单的相分离将Rh纳米颗粒催化剂从产物中分离出来,并直接循环用于下一次运行。
