摘　　要：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.We developed a simple and efficient method to synthesize aromatic azos by hydrogen transfer using palladium(II) acetylacetonate as a catalyst and isopropyl alcohol as a hydrogen source.Further- more,this system also showed catalytic potential for the hydrogenation of carbonyl groups or C=C bonds with yields up to ~97%.
