摘要
用原位红外方法研究了苯甲川九羰基三钴对氨羰化反应的催化机理.分别考察了不同介质以及反应条件下,该催化剂随温度升高的分解情况.并将反应条件下其红外谱图随温度变化的结果与八羰基二钴催化下红外谱图进行了比较.发现一个新催化剂中间体.根据实验结果,提出了反应机理.
The catalytic mechanism of phenylmethylidyntricobalt nonacarbonyl on amidocarbonylation is studied by in Situ infrared rays.The decomposion of catalyzer with the increase of temperature at different medium and reaction condition are recorded. And under the condition the results of its infrared spectrogram varies with the incressing of temperature to be compared with infrared spectrogram catalyzed by cobalt carhonyl. A new intermediate of catalyzer is discovered.According to the testing results, the reactional mechanism is proposed.
