以乙酰丙酮钯作为催化剂前体,异丙醇作为氢源,在碱性的反应过程中原位得到纳米尺度的钯纳米颗粒,并进一步得到钯-氢活性结构,实现硝基的还原及氮氮键的偶联.该催化体系还可以实现C=C和C=O键的有效还原.这类原位得到的钯纳米催化材料表面裸露,因而具有更高的催化活性. Using palladium acetylacetonate as catalyst precursor and isopropanol as hydrogen source, nano-scale palladium nanoparticles were obtained in situ during the basic reaction and the palladium-hydrogen active structure was further obtained to realize reduction of nitro group and nitrogen-nitrogen bond The catalytic system can also achieve the effective reduction of C = C and C = O bonds, and the surface of such in-situ palladium nano-catalytic materials is exposed and thus has higher catalytic activity.
