摘要:

构建了一种由水、1-己醇和Ru纳米(Runano)催化剂组成的温控相转移(TPT)催化新体系,并将上述催化体系应用于查耳酮常压下的选择性加氢反应中。 在优化后的反应条件下,查耳酮的转化率以及查耳酮中CC双键加氢产物二氢查耳酮的选择性均高于99%,Runano催化剂可重复使用6次,查耳酮的转化率和二氢查耳酮的选择性均保持不变。 反应的转化频率(TOF)高于迄今所报道的常压H2下Runano催化剂的最高值,且Ru的流失也得以进一步减少。 此外,上述TPT催化新体系在其它αβ-不饱和酮的常压加氢反应中亦获得了高于99%的转化率和选择性。

Abstract:

A novel thermoregulated phase-transfer (TPT) catalysis system composed of H2O, 1-hexanol and Ru nanocatalyst (Runano catalyst) was developed and utilized for the selective hydrogenation of chalcone at atmospheric H2 pressure. Under the optimal circumstances, both the conversion of chalcone and the selectivity for the product of CC double bond hydrogenation from chalcone were above 99%. The Runano catalyst is conveniently separable from product and directly recycled six times with conversion and selectivity remaining unchanged. The turnover frequency (TOF) was higher than that of previously reported Runano catalyst and the leaching of Ru was further reduced. In addition, this novel TPT catalysis system was also extended to the atmospheric hydrogenation of other α,β -unsaturated ketones with >99% conversion and selectivity.
