[reaction: see text] Iron(III) porphyrin complexes Fe(Por)Cl are effective catalysts for aziridination of alkenes using bromamine-T as the nitrene source. The catalytic system can operate under mild conditions with alkenes as limiting reagents. The aziridination reaction is general and suitable for a wide variety of alkenes, including aromatic, aliphatic, cyclic, and acyclic olefins, as well as alpha,beta-unsaturated esters. For 1,2-disubstituted olefins, the reactions proceeded with moderate to low stereospecificity.
[反应:见正文] 铁(III)卟啉配合物Fe(Por)Cl是以溴胺-T作为氮烯源用于烯烃氮杂环丙烷化反应的有效催化剂。该催化体系能在温和条件下以烯烃作为限量试剂运行。氮杂环丙烷化反应具有普遍性,适用于多种烯烃,包括芳香族、脂肪族、环状和非环状烯烃,以及α,β-不饱和酯。对于1,2-二取代烯烃,反应以中等至低的立体专一性进行。
