The cycloaddition reactions of phenyl azide and butyl azide with monosubstituted electronpoor olefins are highly regioselective (if not regiospecific) and lead to 1,4-disubstituted Δ2-triazolines or products derived therefrom: aziridines, diazocompounds, pyrazolines and 1,4-trisubstituted triazolines. As expected, the latter three products are not formed when a methyl group is introduced in the geminal
的环加成反应的苯基叠氮化物和叠氮化丁酯与单取代electronpoor烯烃是高度选择性(如果不是区域专一性)而导致的1,4-二取代Δ 2 -triazolines或产品由其衍生的:氮丙啶,diazocompounds,吡唑啉和1,4-三取代triazolines 。正如预期的那样,当一甲基组中的烯烃的孪位位置被引入未形成后三种产品,但Δ 2然后被排他地获得-triazolines和氮丙啶。在所有情况下研究了1,4-取代的Δ 2选自苯基叠氮化物衍生只给上热解氮丙啶-triazolines,而那些由烷基叠氮化物衍生被热转化成氮丙啶和烯胺的混合物。
