Testing of synthesized magnetically separable catalyst (Pd-Fe3O4/HPS) was carried out
in the selective hydrogenation of 2-methyl-3-butyn-2-ol to corresponding olefinic alcohol and also in the Suzuki cross-coupling of 4-bromoanisole and phenylboronic acid in a shaker-type glass batch reactor. In the case of selective hydrogenation, the use of Pd-Fe3O4/HPS was found to result in 94% selectivity at 95% of the substrate conversion that is typical for preliminarily reduced Pd/HPS catalysts. Regarding to the Suzuki reaction, relatively high activity of magnetically separable Pd-Fe3O4/HPS was found: 84% conversion of aryl halide was achieved for 30 min of reaction that is in 1.2 times higher than in the case of common Pd/HPS catalyst. Moreover, the catalyst Pd- Fe3O4/HPS allowed repeated use in Suzuki reaction, which makes such catalyst a promising candidate for further study. |
