Investigations into the transition metal catalyzed aziridination of olefins with Bromamine-T as a new source of nitrene is presented in this account. Comparison of Chloramine-T and Bromamine-T in this reaction indicates that the latter is superior as the source of nitrene. Systematic study with several transition metal based catalysts suggests that Cu-halides are the best catalysts. A first report
本报告介绍了使用溴胺T作为新的氮源对烯烃进行过渡金属催化的叠氮化的研究。比较该反应中的氯胺-T和溴胺-T表明后者作为腈的来源是优越的。对几种过渡金属基催化剂的系统研究表明,卤化铜是最好的催化剂。还提出了在微波和超声辐射条件下进行叠氮化的首次报道。在室温下,铜的肉桂酸甲酯与溴胺T的铜催化的叠氮化没有进行,但是在超声辐射下平稳地进行,以选择性地提供反式氮丙啶,而在微波辐射下,得到了顺式和反式异构体的混合物。已经证明,用廉价的漂白粉可以平稳地进行烯烃的叠氮化。该帐户包括Rh催化的与Bromamine-T的苄基插入反应的初步结果。
