In coupling reaction, diazonium ion ua electrophile vim nyob rau hauv diazonium ntsev +ve xwb muaj nitrogen thiab yog li nitrogen yog electron deficiency.
Puas yog diazotization electrophilic?
The diazonium ntsev ua raws li cov electrophile hauv kev sib txuas lus. Muaj ntau cov khoom ntawm kev sib txuas cov tshuaj tiv thaiv yog qhov tseem ceeb dyes. Cov xim xim av ntawm azo compound yog tsim tam sim ntawm cov tshuaj tiv thaiv diazonium ntsev nrog amines lossis phenols.
Puas yog diazonium yog electrophile?
Diazonium ion yog cov khoom siv hluav taws xob tsis zoo thiab yog li coj ua electrophilevim muaj cov nqi zoo ntawm nitrogen. Tab sis vim hais tias ntawm delocalisation ntawm tus nqi zoo ntawm lub nplhaib, qhov no yog qhov tsis muaj zog electrophile. Lub diazonium ion ua haujlwm raws li electrophile hauv cov lus teb azo-dye.
Cov amines twg muab cov tshuaj tiv thaiv diazotization?
Diazotization yog ib qho tseem ceeb ntawm 1° amines Hauv cov txheej txheem diazotization, NH2 pawg tau hloov mus rau diazonium ntsev, R–N2+X− Qhov no yog ua los ntawm cov tshuaj tiv thaiv nitrous acid (HNO 2). Cov ntsev reactive feem ntau tsis cais.
Qhov twg yuav tsis mus rau diazotization?
Benzylamine yog 1∘ aliphatic amiine thiab li no tsis raug mob ntshav qab zib.
