1-Vinylbenzotriazoles give indoles on flash vacuum pyrolysis, but depending on the vinyl substituents side reactions leading to N-phenylketenimines or benzonitrile are observed. The latter process occurs with 1,2-disubstituted vinyl groups and an azatrimethylenemethane is suggested as an intermediate. Ketenimine formation is associated with vinyl groups bearing an α-hydrogen and is the only pathway
1-乙烯基苯并三唑在快速真空热解中产生吲哚,但是取决于乙烯基取代基,观察到导致N-苯基酮亚胺或苄腈的副反应。后者的过程发生在1,2-二取代的乙烯基上,建议使用氮杂三亚甲基甲烷作为中间体。Ketenimine的形成与带有α-氢的乙烯基有关,是观察到的唯一不产生3,3-二甲基-3 H-吲哚的1-(2-甲基丙-1-烯基)苯并三唑的途径。
