摘要:

Heck反应中金属催化是必不可少的,但容易出现金属残留等问题。针对这一问题,开发了一种封装金属催化剂的方式,将金属催化剂与有机硅酮胶均匀混合或将金属催化剂与Fe3O4和有机硅酮胶均匀混合。混合后所制得的负载催化剂或负载磁性催化剂不易破碎,在保持良好的催化活性的同时更容易称重和转移,且易于过滤回收。实验结果表明,有机硅酮胶负载钯催化剂(Pd/C@Glue)经过7次循环使用后,在Heck反应中产物收率仍能达到85%,说明Pd/C@Glue在Heck反应中催化循环效率高。此外,Pd/C@Glue在Heck反应中循环使用7次,其反应液中钯残留量均低于26 ppm,说明在反应液中金属浸出量较低。为了实现催化剂的磁性回收,将有机硅酮胶同时负载Fe3O4和钯催化剂,获得了一种新型磁性负载催化剂(Pd/C-Fe3O4@Glue)。实验结果表明,该磁性催化剂在多次循环使用后,仍具有较好的催化效果。

Abstract:

Metal catalysis plays a crucial role in the Heck reaction, but it is prone to issues such as metal residue. In response to this issue, this article has developed a new way of encapsulating metal catalysts, which involves uniformly mixing the metal catalyst with organic silicone adhesive or uniformly mixing the metal catalyst with Fe3O4 and organic silicone adhesive. The resulting supported catalysts or magnetic supported catalysts are less prone to fragmentation, maintain good catalytic activity, and are easier to weigh and transfer, while also being readily filterable and recoverable. Experiments show that after 7 cycles of use, the organic silicone gel supported palladium catalyst (Pd/C@Glue) can still achieve a product yield of 85% in the Heck reaction, indicating that Pd/C@Glue has a high catalytic cycling efficiency in the Heck reaction. In addition, Pd/C@Glue is cycled 7 times in the Heck reaction, and the residual palladium content in the reaction solution is all below 26 ppm, indicating a low amount of metal leaching in the reaction solution. In order to achieve magnetic recovery of catalysts, a novel magnetic supported catalyst is obtained by simultaneously loading Fe3O4 and palladium catalysts onto organic silicone gel (Pd/C-Fe3O4@Glue) in this paper. Experiments show that the magnetic catalyst has good catalytic effect after multiple cycles of use.
