| Preparation of Benzamide by Hydration of Benzonitrile with Palladium Acetate and Phenylarsonic Acid as Synergistic Catalyst |
|
| 摘要: 以醋酸钯和苯胂酸（物质的量之比nPd∶nAs=3∶2）作为协同催化剂，用于催化苯甲腈水合制备苯甲酰胺。在不额外添加有机溶剂条件下，利用过量苯甲腈兼做溶剂，该反应获得了99%的高产率和100%的苯甲酰胺选择性以及高达186 mol·kg-1·h-1的时空收率，循环反应5轮未发现明显的活性与选择性的降低，催化剂具有良好的循环使用性能。产物的结晶分离研究结果表明苯甲酰胺在0℃的析出百分比为73%，简单过滤即可收集。 |

| Abstract: A new catalytic method for benzonitrile hydration in the absence of solvent was developed by using palladium acetate and phenylarsonic acid (molar ratio nPd:nAs=3:2) as catalyst, which exhibited high catalytic activity (space-time yield (STY)=186 mol·kg-1·h-1) and recyclability. Moreover, the product can be isolated as pure crystals and filtered from the reaction mixture after the reaction system cooling to low temperature (0℃), and the product was characterized by 1H NMR, 13C NMR and FT-IR. |
| Keywords: benzonitrile hydration amide homogeneous catalysis |
