摘要： 首次研究了2-硒代咪唑类化合物催化的一氧化碳对胺的羰基化生成对称脲或口恶唑啉-2-酮的反应,目标产物收率中等到良好. 与传统的单质硒催化的羰基化反应相比,新催化体系有效避免了有恶臭气味的含硒化合物的产生.

Abstract: The1,3-dialkylimidazole-2-selones-catalyzedoxidative carbonylation of organic amines and ethanolamine with carbon monoxide to ureas and2-oxazolidinonewas investigated. Moderate to good product yields were obtained. Odour existing in elemental selenium-catalyzed carbonylation reactions can be avoided in this catalytic system.Key words:1,3-dialkylimidazoleselone;selenium; carbon monoxide; amine; carbonylation; urea; 2-oxazolidinone
