A palladium-catalyzed allylic azidation of alkenes with sodium azide under atmospheric pressure of dioxygen was developed. This methodology provides a new efficient and simple route for accessing allylic azides. Furthermore, the one-pot process consisting of Pd-catalyzed allylic azidation of alkenes and Cu-catalyzed 1,3-dipolar cycloaddition led directly to the 1,2,3-triazole from the alkene. The formed
开发了在大气压双氧下钯与叠氮化钠催化的烯丙基烯丙基叠氮化反应。这种方法为获取烯丙基叠氮化物提供了一种新的有效而简单的途径。此外,由Pd催化的烯烃烯丙基叠氮化和Cu催化的1,3-偶极环加成反应组成的一锅法直接从烯烃中生成1,2,3-三唑。形成的烯丙基叠氮化物也可以原位还原成烯丙基胺或氧化成烯基腈。
