Tirohia te whiti i raro nei, me te ka whakahoki i te pātai i muri i roto i te reo ano rite te whiti: Passage: I runga i te whakawera i te amine tuatahi ki te N-2,4-dinitrophenyl-pyridinium tote (2), te tāpiri o te amine arahi ki te whakatuwheratanga o te mowhiti pyridinium. He tāpiri tuarua o te amine arahi ki te displacement o 2,4-dinitroaniline (5) me te hanganga o te tote König (6a me 6b). Ka taea e te isomer whakawhiti-cis-trans o te tote König (6a) te urupare ma te whakariterite sigmatropic ranei te taapiri nucleophilic o te takawaenga zwitterionic ki te hoatu i te takawaenga cyclized (7). Kua whakaarohia tenei hei waahanga whakatau tere. I muri i te whakawhitinga proton me te whakakore i te amine, ko te ion pyridinium (9) e hiahiatia ana. Pātai: He aha te mea ka tupu ina taapirihia e koe he amine tuatahi?
